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.

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."

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 previous two editions of the "Human Nervous System "have been the standard reference for the anatomy of the central and peripheral nervous system of the human. The work has attracted nearly 2,000 citations, demonstrating that it has a major influence in the field of neuroscience. The 3e is a complete and updated revision, with newchapters covering genes and anatomy, gene expression studies, and glia cells. The book continues to be an excellent companion to the "Atlas of the Human Brain," and a common nomenclature throughout the book is enforced. Physiological data, functional concepts, and correlates to the neuroanatomy of the major model systems (rat and mouse) as well as brain function round out the new edition.
Adopts standard nomenclature following the new scheme by Paxinos, Watson, and Puelles and aligned with the Mai et al. "Atlas of the Human Brain" (new edition in 2007)Full color throughout with many new and significantly enhanced illustrationsProvides essential reference information for users in conjunction with brain atlases for the identification of brain structures, the connectivity between different areas, and to evaluate data collected in anatomical, physiological, pharmacological, behavioral, and imaging studies"

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.

From New York Times bestselling author Sam Kean comes more incredible stories of science, history, language, and music, as told by our own DNA.
In "The Disappearing Spoon," bestselling author Sam Kean unlocked the mysteries of the periodic table. In THE VIOLINIST'S THUMB, he explores the wonders of the magical building block of life: DNA.
There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists.
Kean's vibrant storytelling once again makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.

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.

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.

Spanning an entire century, the Anniversary Collection offers peer-reviewed scholarship in a wide range of subject areas.

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.

This cutting-edge monograph on advanced clinical anatomy and pathoanatomy of the shoulder, written by the world's leading authors, reflects recent significant advances in understanding of anatomy and pathology. It is beautifully illustrated with exquisite photographs of anatomical specimens, and images from arthroscopy, histology, and radiology complete the picture. The accompanying text brings out the clinical, biomechanical, and functional relevance and focuses on aspects important to the high-performance athlete. In addition, the book closely assesses how each component of the normal anatomy responds to trauma, disease, and degeneration. The finer points of the pathoanatomy are demonstrated with clinical cases, histology, radiology, arthroscopy, and open surgery. The text details how the pathoanatomy affects the patient presentation, clinical examination, and imaging. It is also explained how the pathology affects the natural history and the outcome of physical therapy and influences recommendations for surgical treatments. This book will be of immense value both to trainees and to specialists who manage disorders of the shoulder, including orthopedic surgeons, sports physicians, and physiotherapists. It will also be of great interest to anatomists and pathologists.
