Over the last years, numerous studies have provided new insights into the structural and functional organization of the human cortical motor system. The data reviewed in this book indicate that striking similarities have been found between humans and non-human primates.
This book focuses on the challenges to biomedical education posed by the lockdowns and restrictions to on campus teaching brought about by the COVID-19 pandemic and highlights the tools and digital visualization technologies that have been successfully developed and used for remote teaching. Biomedical education for science, medical, dental and allied health professionals relies on teaching visual and tactile knowledge using practice-based approaches. This has been delivered for decades via on-campus lectures, workshops and laboratories, teaching practical skills as well as fundamental knowledge and understanding. However, the arrival of the COVID-19 pandemic meant that education across the globe had to pivot very quickly to be able to deliver these skills and knowledge in a predominantly online environment. This brought with it many challenges, as Higher Education staff, had to adapt to deliver these visual subjects remotely. This book addresses the challenges and solutions faced by Higher Education staff in teaching visual content in distance education. Chapters include literature reviews, original research, and pedagogical reflections for a wide range of biomedical subjects, degrees such as medicine, dentistry and veterinary sciences with examples from undergraduate and postgraduate settings. The goal of the book is to provide a compendium of expertise based on evidence gathered during the COVID-19 pandemic, as well as reflections on the challenges and lessons learned from this dramatic shift in teaching. It also presents new examples of best practices that have emerged from this experience to ensure that they are not lost as we return to on-campus learning in a new era of biomedical teaching. This book will be of interest to anyone looking for a helpful reference point when designing online or blended teaching for visual practice-based subjects.
The refereed proceedings of the Second International Workshop on Functional Imaging and Modeling of the Heart, FIMH 2003, held in Lyon, France in June 2003. The 29 revised full papers presented together with 2 invited papers were carefully reviewed and selected for presentation. The papers are organized in topical sections on anatomy extraction and description, modeling of the cardiac mechanics and functions, electro-physiology and electro- and magnetography, motion estimation, image registration and image analysis, and data acquisition and experimental and modeling issues.
The numerous and meticulously exposed findings are the very latest and of practical use for the cardiologist who is interested in new, morphologically-based diagnostics and the establishment of an exact anatomical basis for modern non-invasive therapy; for the radiologist who strives to obtain precise anatomical data, accurate and angiographical evaluations and diagnoses; for the cardiac surgeon, who strives, through precise and safe approaches in operations on the heart, to diminish surgical risks and increase the benefit of surgery to the patient. The review includes an great variety of new findings which relate to the greater (major) and smaller (minor) cardiac venous system and narrow a gap in the rather incomplete knowledge of the venous drainage of the human myocardium. A number of the results may help to achieve the success of the rather new technique of coronary sinus catheterization and reperfusion of the cardiac veins.

This book is a concise summary of the present knowledge about skeletal muscle fibres. The fibre types aare characterized from different points of view. The difficulties and possibilities of classifying muscle fibres in distinct non-overlapping types are shown. A main emphasis is put on metabolic fibre typing by cytophotometry as well as the adaptability of a given fibre type to altered physiological and pathological conditions. Extensive analyses of several rat hindlimb muscles revealed regional differences of fibre properties within the muscles and showed the influence of ageing, myopathy, hypoxia, diabetes and Ginkgo biloba-treatment on the different fibre tyypes.
This work is not an anatomical atlas nor textbook (like that of McAlpine and Anderson) nor an angiographical atlas (like that of Vlodaver et al.); it is a short and comprehensive survey of the many variations of the intrinsic cardiac vessels. The reader's attention is focused on the numerous structural details and peculiarities of the human coronary arteries. The many unique features have been revealed by meticulous dissection and present an excellent documentation. All in all, this study represents an up-to-date review of morphology of the coronary arteries.
The alternation between urine retention and discharge several times daily from a nappy to the cessation ofall vital functions only becomes the subject baby's first wet of greater attention if the harmony of the structure and function of the bladder is disturbed. Functional disturbances of the lower urinary tract are not only of great socio-economic importance, but are also a considerable personal burden for the patient. Hence urinary incontinence is rightly classified as a severelydisabling illness (Hauri 1985). Opinions still differ regarding the morphological basis ofurinary continence.The Terminologia Anatomica (1998) defines a musculus sphincter urethrae internus (in- ternal urethral sphincter) and a musculus sphincter urethrae externus (external ure- thral sphincter),which in the older nomenclature were known as musculus sphincter vesicae and musculussphincterurethrae,respectively.The internal urethral sphincter isascribed apurelyinvoluntaryandthe externalurethralsphincterapurelyvoluntary innervation. The significance of the musculature of the pelvic floor for maintaining urinarycontinence has notyetbeen ascertained. Duringnumerous urologicaloperations (forinstancetransurethralresectionofthe prostate and bladder neck incisions), the only involuntarily innervated sphincter at the collum vesicae,the internalurethralsphincter,is partiallyorcompletelydestroyed (Fig. 27C,D).All the patients remain continent as long as the externalurethral sphinc- ter remains intact.Howcan apurelyvoluntarilyinnervated sphincterlikethe external urethral sphincter ensureconstant continence in such cases? Improving the continence rate after radical surgery is a key topic of urological research. The incontinence rate after radical prostatectomy is still between 8.1% (third-degree incontinence) and41.4% (first- to second-degree incontinence; Rudyet al. 1984; Igel et a1.1987; Schroderand Ouden 1992).
In the medical imaging field, clinicians and researchers are increasingly moving from the qualitative assessment of printed images to the quantitative evaluation of digital images since the quantitative techniques often improve diagnostic accuracy and complement clinical assessments by providing objective criteria. Despite this growing interest, the field lacks a comprehensive body of knowledge. Filling the need for a complete manual on these novel techniques, Quantifying Morphology and Physiology of the Human Body Using MRI presents a wide range of quantitative MRI techniques to study the morphology and physiology of the whole body, from the brain to musculoskeletal systems. Illustrating the growing importance of quantitative MRI, the book delivers an indispensable reference for readers who would like to explore in vivo MRI techniques to quantify changes in the morphology and physiology of tissues caused by various disease mechanisms. With internationally renowned experts sharing their insight on the latest developments, the book goes beyond conventional MRI contrast mechanisms to include new techniques that measure electromagnetic and mechanical properties of tissues. Each chapter offers comprehensive information on data acquisition, processing, and analysis techniques as well as clinical applications. The text organizes the techniques based on their primary use either in the brain or the body. Some of the techniques, such as diffusion-weighted imaging and diffusion tensor imaging, span several application areas, including brain imaging, cancer imaging, and musculoskeletal imaging. The book also covers up-and-coming quantitative techniques that explore tissue properties other than the presence of protons (or other MRI-observable nuclei) and their interactions with their environment. These novel techniques provide unique information about the electromagnetic and mechanical properties of tissues and introd
The basal ganglia are involved in complex brain functions, from voluntary movement control to learning and reward processing, and they are implicated in numerous neurological and psychiatric disorders. Information from the cerebral cortex and thalamus is conveyed to basal ganglia nuclei via glutamate release, while dopamine from the midbrain is released in close proximity to glutamate. At the heart of both function and dysfunction of basal ganglia circuits is the interaction of these two neurotransmitters, dopamine and glutamate. Elucidating the relationship between their molecular and cellular effects and behavioural significance has been challenging, but in the past 5-10 years, improved labeling, imaging, recording, and genetic manipulation approaches have yielded new information on how dopamine and glutamate interact to generate the circuit activity underpinning basal ganglia function. Dopamine-Glutamate Interactions in the Basal Ganglia synthesizes this recent research from the level of receptor molecules all the way to complex behaviours and disease. Current insights from research on individual neurons and synapses, detailed circuit analysis, and learning and action functions of the basal ganglia are presented against a historical perspective. The book also discusses compromised dopamine-glutamate interaction in disorders of basal ganglia function, including Parkinson's disease, Huntington's disease, and drug addiction.
Preparatory work for this monograph started in 1988 and 1989. The motive was provided by certain incongruities in the illustra- tion of descensus testis for the chapter "Entwicklung der Genital- organe" in the book Humanembryologie. The evoked discussion was reason enough for our own re- search on the phenomenon and uncertainties of testicular des- cent in human. The basis ofthese investigations was the collection of human embryos founded by Prof. Hinrichsen in 1970 at the Department of Anatomy and Embryology, Ruhr-University Bo- chum. The preparation of the material used in this paper has been done with the help of many staff members of our department to whom we feel obliged. We are especially indebted to Prof. Hin- richsen who prepared the foetuses and took the first steps of this project. We wish also to acknowledge Dr. Heinz Jiirgen Jacob for careful fixation and microdissection of specimens intended for scanning electron microscopy. Weare also grateful to Mrs. Vera Mannheim for her involvement and her sensitivity in making scanning electron micrographs, and Mrs. Antje Jaeger for provid- ing an expert and skilful photographic technique especially in the setting up of micrographs. Our thanks are also due to Mrs. Marion Kohn for skilful technical assistance and to all those technical assistants who worked in our department during the past 25 years and who were engaged in providing the serial sec- tions. The English text has been thoroughly revised by Prof. Dr.
The studies presented in this monograph concentrate on the glycoconjugate characterisation of the mouse and human GALT and on the overlying follicle-associated epithelium (FAE), in order to identify their cell-specific carbohydrate residues.
The objective of the present work is to review the existing literature on joint incongruity, cellular mechano-transduction, and computer simulations of mechano-adaptive bone remodelling, and to quantitatively assess the effect of incongruity on load transmission and subchondral mineralisation. Idealised computer models of incongruous joints and a specific anatomically based model of the humero-ulnar joint articulation were analysed with the finite element method, and the results directly compared with experimental and morphological data.
This classification represents a project aimed at bringing together the variety of ways thymic epithelial neoplasms have been classified. It focuses on their growth characteristics, and cytoarchitectural features . The classification, though restricted to the thymic region rather than the mediastinum in general, also covers neuroendocrine, germ cell, lymphoid, and stromal tumours, as well as tumour-like lesions and the neck tumours of thymic or related branchial pouch derivation.
The 1973 WHO classification of bladder tumours anticipated a probable need for eventual revision of the criteria for diagnosing papillary and flat bladder neoplasia. A workshop sponsored by the WHO consisting of pathologists, urologists, cytologists, oncologists and basic scientists interested in bladder tumours addressed this subject, and after a follow- -up meeting sponsored by the International Society of Urological Pathology, the classification and terminology used in this text were agreed upon. A major change is in the introduction of a new category: papillary urothelial neoplasm of low malignant potential. Many of the tumours previously designated as papillary transitional cell carcinoma, grade I now fall into that category. Another major change is in the designation of flat lesions, and this includes a definition of carcinoma in situ. Furthermore, a number of variant forms of urothelials carcinomas are included as well as new entities not recognized when the 1st edition was issued.

What is the function of the mammillary body? Which information is passed through the cuneate fasciculus or the internal arcuate fibers? Which hormones are produced by the paraventricular hypothalamic nucleus? Which nerves and vessels run through the jugular foramen? Which parts of the body are innervated by the accessory nerve? Which cortical regions are affected by a dysfunction of the central sulcus artery?These are frequently asked questions to which a short and precise answer is seldom found in textbooks or other scientific works. These questions - and more - are now answered in the long-awaited Dictionary of Human Neuroanatomy. It will be a useful companion for everyone looking for precise and functional definitions of terms in the field of neuroanatomy, and is absolutely essential for those studying neuroanatomy, and for quick reference.
}This eloquent book takes us on a spell-binding journey into the workings of our bodies in health and disease. Dr. Charles A. Pasternak captivates us with his vivid and even poetic explanations of what keeps us healthy and vital, and what tears away at our health. He possesses the gift for rendering complex topics clear and lyrical, as in the ways our molecules interact with one another to decide the fate of our heart, brain, and lungs---whether we live or die.Why does disease rear its ugly head? Why does cancer take hold in some of us and pass by others? What roles do nutrition and stress play in determining our chances for a long, fulfilling life? Can we hold our eventual demise at bay by trying novel drugs and therapies? Dr. Pasternak also explores to what extent the illnesses we sufferand even our level of intelligenceare dependent on the genes we inherit from our parents, or the food we eat, or even the environment we inhabit. The story of our bodies is a true saga that has never before been so engrossingly told. }
This expanded edition includes a new introduction by John Nix as well as a new appendix offering case studies and practical insights from teachers about how Barbara Doscher has impacted their voice instruction. An understanding of how the singing voice functions should be a prerequisite for all those who wish to teach singing. And fundamental to any safe and efficient teaching method is the recognition that the singing voice is a functional unit. Consequently, this second edition, like the first, describes the anatomy and physiology of breathing and phonation and examines the acoustical laws necessary for an understanding of resonation. It is designed primarily as a textbook for college vocal pedagogy courses. The book includes detailed illustrations and an expansion of the appendix on vocal misuse and abuse, including data on subglottic air pressure/air flow ratios, the phonatory mode known as belting, and the aging voice, especially as it is affected by hormonal changes in the body. It also feature an extensive bibliography.
Since the 1980s, ankle arthroplasty has been considered a dubious treatment for painful and degenerated joints. Many of the concerns that existed previously have been solved today. Prosthetic replacement of other joints also took a long time before reaching their present successful status. This is the first book to deal with ankle arthroplasty. International experts have given their opinion on (i) the kinematics of the ankle; (ii) the basics of replacing the ankle joint; and (iii) the current status of several modern ankle-prosthesis designs. A better understanding of the ankle kinematics, alignment techniques and biological stabilisation and the results of newer designs have changed the former attitude worldwide. The content of this book bears evidence for this change in opinion.
This book reflects practical approaches to answering a variety of biological and medical questions using DNA fingerprinting and genetic profiling in a broad sense that also includes statistical evaluation of the data. It has been written for biology, biochemistry and medical students, graduates, postdoctoral fellows, academic teachers and for all researchers in the theoretical and applied sciences wherever genetic identification and relationship analysis are required.
Investigations on anatomical specimens have demonstrated that the subchondral mineralization does indeed show regular distribution patterns from which conclusions about the mechanical situation within an individual joint may be drawn. Since radiographical densitometry and histological methods are only available for determining the adaptive reaction of the bone to the mechanical situation in a joint after death, the information obtained applies only to an end situation and tells us nothing about the development of the changes with time. Furthermore, investigations carried out on human specimens by radiographical densitometry mostly apply to samples of a particular age, since such specimens can be acquired only from departments of pathology, forensic medicine or anatomy.
Glomerular flltration represents one of the basic mechanisms in the function of an organism. Our understanding of this process is still quite fragmentary. Regulation of blood flow and pressure, together with regulation of the ultraflltration coefficient (which is an attribute of the flltration barrier), are the two fundamental mechanisms accounting for maintenance and adaptability of glomerular flltration. Regulation of glomerular blood flow is generally considered to result from an interplay between afferent and efferent glomerular arterioles, and much progress has been made recently in understanding this interplay (Navar et al. 1996). The present study provides a detailed structural description of the glomerular vascular pole of rat. The results of this study appear to be relevant for several open questions of glomerular function. First, the interaction between afferent and efferent arterioles in regulating glomerular blood is generally understood to occur between the preglomerular and the postglomerular portions of these vessels. As shown in the present study, the structural elaborations of these arterioles and the spatial relationships between them within the glomerular hilum strongly suggest an interplay also at this site. Moreover, the current understanding of glomerular blood flow regulation by tuning the interplay between afferent and efferent arterioles is exclusively based on signals whose regulatory loops are established in follow-up events outside the glomerulus (tubuloglomerular balance, tubuloglomerular feedback). |
