This chart shows medial and lateral views of the bones and
ligaments of the foot and ankle, and illustrates nerve and blood
supply to this region, including plantar view of arteries and
nerves. It also shows common fractures and sprains and anterior
impingement syndrome. Anatomy and Injuries of the Foot and Ankle
describes and shows locations of forefoot, midfoot, and hindfoot
injuries such as bunions, Morton's neuroma, bunionette (Tailor's
bunion), hammertoe, Jones' fracture, Chopart avulsion fracture,
Lisfranc dislocation, metatarsal stress fracture, Achilles' tendon
rupture, tarsal tunnel syndrome (which is becoming more common
among snowboarders), calcaneal fracture and plantar fasciitis with
hell spurs. The chart also visually and textually describes
movement about the ankle: inversion, eversion, dorsiflexion, and
plantar flexion.
In the past decennia nonhuman primates have been increasingly used
for research purposes in various scientific fields. Much interest
has been focused on this group of animals in general and on the
rhesus monkey in particular because of its close phylo genetic
relationship with man. In some fields of research, however, such as
embryology and microscopic anatomy, much less attention has been
paid to nonhuman primates, probably because of the expense involved
in the collection of the extensive material needed. On the other
hand, teratological and experimental embryologic studies must be
based upon a thorough knowledge of the normal ontogenesis since
only in that way can a reliable distinction be made between normal
and abnormal or induced develop ment. Each ontogenetic study
essentially consists of a comparison of different deve lopmental
stages. In most reports dealing with the development of individual
organs or their subunits the material used is classified according
to the estimated age or the length of the embryos. These criteria,
however, are not valid, since considerable varia tion in
developmental stage occurs between animals of the same age even
between littermates and between animals of the same length.
Therefore a method is needed for assigning embryos to successive
developmental stages that are defmed on the basis of extemal and
internal characteristics. This type of classification was
elaborated by Stree ter (1942, 1945, 1948,1951), who arranged human
embryos into developmental hori zons numbered XI through XXIII."
In recent years the inferior olive and its projection to the
cerebellum have attracted considerable interest. Numerous
experimental anatomic and electrophysiologic studies have been
undertaken, and much new information has been brought forward. Many
apparently discordant observations have been reported however, and
on many points the data obtained by the use of different methbds
and approaches appear to be diffi cult to reconcile. Much of the
interest in the olivocerebellar projection concerns the
topographical localization within the projection. Particularly as a
result of research in recent years the pattern of localization has
turned out to be far more complex than previously be lieved. It was
found useful, therefore, to attempt a review of the subject in the
hope that a critical analysis of available observations might make
it possible to obtain an integrated picture of the olivocerebellar
projection and perhaps fmd some basic principles in the
organization of this fiber system. As will be seen, our attempt has
been only partly successful. There are still riddles that remain to
be solved. In the present review attention will be focused on
problems related to the locali zation within the olivocerebellar
projection, particularly its anatomic aspects. An extensive review
of the physiology of the inferior olive has been published recently
by Armstrong (1974), who considers some anatomicophysiologic
correlations as well. Physiologic fmdings will be referred to here
mainly in relation to our main theme."
Wilhelm His, one of the founders of developmental neurobiology, was
convinced "that the processes of generation and development obey
fundamental and simple laws and submit to the general laws of
nature" (His 1901). Therefore, we should be able to find immediate
conditions, dependencies and rules determining the de velopment of
an organic form. With this in mind, His (1874) defined the task of
embryology as follows: "Developmental biology is essentially a
physiological science; it has not only to describe how each
individual form develops from the egg, it has to derive this
development in such a way that each developmental stage together
with all its specialities appears as a necessary consequence of the
immediately pre ceding stage . . . Only if developmental biology
has given a perfect physiological deriva tion for any given form,
has it the right to say that it has explained this individual form.
" The ultimate aim of a physiological derivation would be that laws
of growth valid for organic ,beings can be expressed as
mathematical formulae (His 1874). To exemplify this, he formulated
a universal and purely formal law of growth in mathematical terms
making the comment: "I now suggest that the body form follows
immediately from germinal growth and can be derived from the given
germinal form according to the laws of growth. My interest is,
therefore, firstly to detect the law of growth empirically and
secondly to derive consecutive forms of the developing or ganism by
applying this law.
The afferent connections of the cerebellar cortex of the cat have
been extensively in- vestigated by Alf Brodal and his collaborators
using retrograde degeneration methods. These experiments (reviewed
in Larsell and Jansen 1972) established that cerebellar corti- cal
afferents arise from widespread areas of the brain stem and spinal
cord. Brain stem nuclei shown to provide input to the cerebellar
cortex included the pontine nuclei, the medial and descending
vestibular nuclei, vestibular cell group x, the lateral reticular
nucleus, the perihypoglossal nuclei, the paramedian reticular
nucleus, the inferior olive, and the external cuneate nucleus. In
addition, the red nucleus and certain of the raphe nuclei were
thought to send fibers to the intracerebellar nuclei, but not to
the cortex. With the advent of the horseradish peroxidase (HRP)
technique, new information on the distribution and organization of
cerebellar cortical afferents has recently be- come available. Thus
Gould and Graybiel (1976) demonstrated that afferents to the cat
cerebellar cortex arise from a previously undescribed lateral
tegmental cell group at the level of the isthmus and from the
intracerebellar nuclei, as well as from the classic precerebellar
nuclei. Moreover, these studies showed that fibers from the
vestibular nuclei, previously thought to be distributed only to the
flocculonodular lobe and uvula, reach widespread areas of the
cerebellar cortex. Experiments by other investi- gators have
established that the cerebellar cortex of the cat receives
afferents from cer- tain of the raphe nuclei (Shinnar et al. 1975;
Taber Pierce et al.
Gastroenterologists require detailed knowledge regarding the
anatomy of the GI system in order to understand the disturbances
caused by diseases they diagnose and treat. Gastrointestinal
Anatomy and Physiology will bring together the world s leading
names to present a comprehensive overview of the anatomical and
physiological features of the gastrointestinal tract. Full colour
and with excellent anatomical and clinical figures throughout, it
will provide succinct, authoritative and didactic anatomic and
physiologic information on all the key areas, including GI
motility, hepatic structure, GI hormones, gastric secretion and
absorption of nutrients. GI trainees will enjoy the self-assessment
MCQs, written to the level they will encounter during their Board
exams, and the seasoned gastroenterologist will value it as a handy
reference book and refresher for re-certification exams
Studies on cell kinetics in untreated animals have for the most
part been done on or gans in which many proliferating cells can be
found. In general the proliferating cells have been identified
either in histologic sections as mitoses or by autoradiography as
labeled interphase cells following the injection of a labeled
precursor of DNA, such as 3H_ or 14C-thymidine (TdR). A great many
proliferating cells can be observed in the rat and mouse brain
during the embryonic period and for a short time after birth, and
many studies on cell kinetics have been performed for this phase of
life. By contrast, very few proliferating cells are found in the
brain of adult rodents (except for the subependymallayer, see
below). As a result, only isolated studies have been done on cell
kinetics during this period. Al though there is an increase in
proliferating cells in adult animals which had been pre treated (e
g. , by wounding, X-irradiation, viral infection, withdrawal of
water), this proliferation too has not been investigated in detail.
A number of studies have been done since 1959 on the proliferation
of cells in the sub ependymal layer of the lateral ventricles of
the forebrain. This cell type is well suited for such
investigations because mitoses can be found there even in animals
which are quite old. Since the studies ofLe blond and co-workers

underlying the efficiency and adaptability of cellular meta bolism
is the structural compartmentalization of the cell. Only through
compartmenta lization can reaction components be kept apart prior
to their reaction, isolated from other "reaction spaces" during the
course of their reaction, and the reaction products incorporated
into designated structures or transported to remote parts of the
cell. Thus, the partitioning of the cellular substance into
countless membranous spaces corresponds to the spatial segregation
of reaction components, and the dynamics of intracellular membrane
systems is an expression of ever-changing equilibrium condi tions
and the continuous formation of new reaction spaces. It has been
shown with some certainty that many of the processes in membrane
dynamics can take place only with the aid of contractile proteins
such as actin, myosin, and tubulin."
The earliest mention of a cell sheath enveloping the body of the
neurons in sensory ganglia is probably the following description by
Valentin: "Sowohl die Kugeln der Be- legungsformation 1 , als die
Primitivfasem, werden von eigenthi. imlichen, sie isolirenden
Scheiden umgeben, welche aile Stufen der Dicke von einer fast gar
nicht mehr wahr- nehrnbaren Zartheit bis zu einer ziemlich
bedeutenden Starke durchlaufen. Diese Hill- len sind aber immer
zellgewebeartiger Natur" (1836, p 162). In some illustrations of
the above mentioned paper the nuclei of the satellite cells
adjacent to the surface of the nerve cell body, both in the
trigeminal ganglion and in the ganglia of the vegeta- tive nervous
system, are clearly shown (Fig. lA). The author, however,
miSinterpreted these nuclei as pigment granules
(Pigmentkorperchen). A little later, Remak (1838) denied the
existence of the perineuronal cell sheath. This prompted a ready
reply from Valentin (1839), who offered a more detailed description
of the perineuronal cell sheath, illustrated it with new drawings
(Fig. IB), and gave a correct interpreta- tion of the nuclei. In
fact, he wrote: Fig. lA-B. Nerve cell bodies of sympathetic ganglia
with the nuclei of the satellite cells on the neuronal surface.

A vascular system consists of a supplying arterial and a draining
venous part which are connected by a terminal vascular network. The
arterial segment can be characterized according to the structural
features of the vessel wall. However, it is sometimes diffi- cult
to distinguish the capillary from the postcapillary vessels on the
basis of structural features alone. On the other hand, physiologic
qualities such as permeability can hard- ly be associated with an
equivalent histologic pattern of the vessel wall (lllig 1961;
Rhodin 1967, 1968; Hauck 1971; Westergaard 1974). A defmition of a
vascular seg- ment based on biologic significance should combine
morphological and functional qualities of the vessel walls. During
the ontogeny of the mammalian organism a variety of vascular
patterns (e. g. , distribution of arteries and veins, arrangement
of the capillaries) has been formed typical of each organ (Wolff et
al. 1975; Baez 1977). The capillaries connect the feed- ing
arterioles and the collecting venules in two different ways
according to the branch- ing pattern of the terminal vessels (Hauck
1975, Wolff et al. , 1975). The arterioles and venules are directly
connected by capillary segments. Consequently a terminal vessel
called arteriovenous (a-v) capillary results, or a closely meshed
capillary network is de- veloped which connects arterioles and
venules by a variable number of small capillary branches arranged
parallel to the preexisting a-v capillary.
Anatomy to most people is a subject which suggests the cutting up
of dead bodies (the word literally means cutting up). In addition
it is generally known that Vesalius published a book in 1543 in
which much of the human body was described in detail and more or
less accurately. A subject which is dead and ancient fre quently
has little appeal especially if it appears to involve learning a
large amount of factual information. For many years anatomy has had
to struggle with these disadvantages and at times one has had the
impression that there is almost a conspiracy on the part of
everyone to suggest that anatomy is unnecessary. There is no doubt,
however that a knowledge of the structures of the body, for that is
what anatomy is, whether it is what can be seen with the naked eye
or with different kinds of microscope, is an essential preliminary
and corollary to the understanding of the functions of the body. It
was no historical accident that Vesalius, the anatomist, preceded
Harvey, the physiologist. No apology need be made for trying to
present the basic facts of anatomy to anyone interested in the
human body and to members of any profession which will have to cope
with the physical and mental problems of children, men and women in
health and in sickness. It is not intended that the reader should
know every thing contained in this book."

Although a human embryo possesses so much grace that the untutored
spectator can only admire it in awe, this minute and humble embryo
is still almost unknown to many. For some, it seems to belong to
the animal kingdom only; others see in it man in his most
primordial and elementary aspect. The early life of man thus has
become a problem. The development of man as individual (individual
development) begins with fertilization. The following pages,
therefore, concentrate above all on the develop- ment from the ovum
to the embryo. The description given below of the ontogenesis of
the human embryo and its early functions has been completely
documented by our human-embryological collection. Numerous original
pho- tographs and systematically revised drawings were pub- lished
in 1973 under the title Die praenatalen Organsys- teme des Menschen
(The Prenatal Organ Systems of Man); the supplementary scientific
commentaries were published in 1977 in Biokinetics and Biodynamics
of Human Differentiations. A complete series of portrait
illustrations is located at the Science Centre in Toronto, Canada.
The cat has been used as a subject for dissection in the study of
mammalian anatomy for almost two centuries. The very popular
Pictorial Anatomy of the Cat by Stephen G. Gilbert, originally
published in 1967 and now in its 12th printing, has been used in
countless laboratories as a guide to dissection and supplement to
introductory textbooks. Outline of Cat Anatomy is an abridged
version of the original guide, modified for practical use in
one-semester courses. It employs anatomical terms used in human
rather than veterinary anatomy and includes illustrations of human
anatomy that may be compared with those of the cat, especially
useful for the many students who do not have access to human
dissections. Gilbert's earlier Pictorial Anatomy of the Cat is "an
excellent, well-illustrated dissection guide for use in courses in
comparative anatomy. The text is informative and accurate, and
instructions for dissection are clear and helpful. . . . Highly
recommended." -Choice

Principles of Anatomy according to the Opinion of Galen is a
translation of Johann Guinter's textbook as revised and annotated
by Guinter's student, Andreas Vesalius, in 1538. Despite Vesalius'
fame as an anatomist, his 1538 revision has attracted almost no
attention. However, this new translation shows the significant
rewrites and additional information added to the original based on
his own dissections. 250 newly discovered annotations by Vesalius
himself, published here in full for the first time, also show his
working methods and ideas. Together they offer remarkable insights
into Vesalius' intellectual biography and the development of his
most famous work: De humani corporis fabrica, 1543. An extensive
introduction by Vivian Nutton also provides new information on
Johann Guinter, and his substantial use of Vesalius' work for his
own revised version of the text in 1539. Their joint production, a
student textbook, is set against a background of the development of
Renaissance anatomy, and of attitudes to their ancient Greek
predecessor, Galen of Pergamum. This text will be of great interest
to historians of science and medicine, as well as to Renaissance
scholars.
The endothelium is an excellent example of where biology meets
physics and engineering. It must convert mechanical forces into
chemical signals to maintain homeostasis. It also controls the
immune response, drug delivery through the vasculature, and cancer
metastasis. Basic understanding of these processes is starting to
emerge and the knowledge gained from research is now being used in
applications from drug delivery to imaging modalities. This book
reviews current knowledge in mechanobiology of the endothelium and
its implications for the development of theranostic devices.
According to the classical theory of functional structure of bone
which was developed by J. Wolff (1884, 1892) and W. Roux (1895)
following the investigations of the functional architecture of the
substantia spongiosa by H. von Meyer (1867), bone is "functionally"
laid down in gross form as well as in minute architecture in
accordance with the "maximum-minimum-law." As a result of
functional adaptation, a maximum of efficiency is achieved with a
minimum of material (Kummer, 1962a). In this sense functional
adaptation is a reaction of adaptation of the idiotype-within the
bounds of the reaction norm-to a changed internal environment, that
is in this case an adaptation to changed mechanical stresses. 1.
The Formation of the Normal Femur Shape The heredity basis of shape
characteristics of human femora is really unknown. Identical twins
show a significant lower variability of length of femur than
binovular twins. Population variability of length of femur due to
heritability may exceed twice the variability due to environmental
factors (Knussmann, 1968). A significant part of the total
variation of femur shape characteristics remains therefore
unexplained supposing that the sources of variation due to
heritability and environmental factors are also nearly the same for
the other traits.
The prime purpose of this paper is to look at the region of brain
which many authors call 'paleocortex' and to ask how much of the
area it embraces can be described properly as cortex. Before this
can be considered it is necessary to have some idea of what
constitutes a cortex. Therefore, in the first part of the paper the
criteria used in constructing classifications of cortex are looked
into. Also considered is the meaning of classifications such as
'paleocortex'. Is it relevant to define cortex in this way? How
does this view correlate with a functional approach? The second
purpose of this paper, of equal importance to the first, is to
review terminology. Each area of' paleocortex' has a review
introduction that endeavoors to cut through the existing jungle of
terms and usage and to provide a clear account of the area in
question, prior to examining its standing as cortex. The term
'paleocortex' is in common use and for this reason it is worth
close examination. Kappers (1909) first created the term to
supplement the earlier division of cortex-into archicortex and
neocortex-introduced by Elliot Smith. Kappers applied the term to
the mantle layer of the most primitive vertebrates (cyclostomes and
selachians), the whole of which receives secondary olfactory
fibres.
The author of a number of acclaimed, best-selling surgical atlases
has collaborated again with an award-winning artist to produce
