PREFACE High-Yield Gross Anatomy addresses many of the recurring clinical themes of the USMLE Step 1. The information presented in this text prepares you to handle not only the clinical vignettes found on the USMLE Step 1, but also the questions concerning basic gross anatomy concepts. Like the USMLE Step 1, the discussions are comprehensively illustrated with a combination of drawings, MRIs, CT scans, radiographs, and cross-sectional anatomy. This edition is particularly excit- ing because we have included colored diagrams and figures to assist the learning process. In addition, High-Yield Gross Anatomy directly addresses clinical issues and common clinical techniques (e.g., liver biopsy, tracheostomy, and lumbar puncture) that require knowledge of basic gross anatomy to deduce the correct answer. For High-Yield Gross Anatomy, Fifth Edition, Dr. Thomas Louis has again contributed his consider- able gross anatomy teaching experience to improve and narrow the focus of the book. Dr. Louis has taught gross anatomy for about 30 years in both cadaver-dissection and computer-assisted distance- learning gross anatomy courses. He has been a leader in developing computer-assisted distance learn- ing at the Brody School of Medicine and has received national recognition for his efforts. Dr. Louis used High-Yield Gross Anatomy in his physician assistant gross anatomy course for 4 years with excellent success and supplemented the clinical anatomy presented in the book with critical basic anatomy figures and diagrams to assist students in learning the gross anatomy relationships of these clinically relevant areas. Dr. Louis and I have added some of these colored figures and diagrams to further enhance your understanding. I would appreciate your comments or suggestions about this book, especially after you have taken the USMLE Step 1, so that future editions can be improved and made more relevant to the test.

  • An Anatomical Exploration Into the Variable Patterns of the Venous Vasculature of the Human Kidney
    AN ANATOMICAL EXPLORATION INTO THE VARIABLE PATTERNS OF THE VENOUS VASCULATURE OF THE HUMAN KIDNEY. by KAPIL SEWSARAN SATYAPAL Submitted in partial fulfilment of the requirements for the degree of DOCTOR OF MEDICINE in the Department of Surgery University of Natal Durban 1993 To my wife Pratima, daughter Vedika, son Pravir, and my family. m ABSTRACT In clinical anatomy, the renal venous system is relatively understudied compared to the arterial system. This investigation aims to clarify and update the variable patterns of the renal venous vasculature using cadaveric human (adult and foetal) and Chacma baboon (Papio ursinus) kidneys and to reflect on its clinical application, particularly in surgery and radiology. The study employed gross anatomical dissection and detailed morphometric and statistical analyses on resin cast and plastinated kidneys harvested from 211 adult, 20 foetal and 10 baboon cadavers. Radiological techniques were used to study intrarenal flow, renal veins and collateral pathways and renal vein valves. The gross anatomical description of the renal veins and its relations were confirmed and updated. Additional renal veins were observed much more frequently on the right side (31 %) than previously documented (15.4%). A practical classification system for the renal veins based on the number of primary tributaries, additional renal veins and anomalies is proposed. Detailed morphometric analyses of the various parameters of the renal veins corroborated and augmented previous anatomical studies. Contrary to standard anatomical textbooks, it was noted that the left renal vein is 2.5 times the length of its counterpart and that there are variable levels of entry of the renal veins into the IVe.

  • GROSS ANATOMY and CLINICAL PROBLEMS of CNS BLOOD SUPPLY and GLOSSOPHARYNGEAL NERVE © 2019Zillmusom
    GROSS ANATOMY AND CLINICAL PROBLEMS OF CNS BLOOD SUPPLY AND GLOSSOPHARYNGEAL NERVE © 2019zillmusom I. OVERVIEW - Branches to CNS are described as arising from two sources: Vertebral and Internal Carotid arteries. A. Spinal Cord - Anterior Arteries and Posterior Spinal Arteries form as branches of Vertebral Arteries; however, most blood supply to the spinal cord is derived from Radicular arteries (branches of segmental arteries that enter via Intervertebral Foramina) B. Brain - Common Carotid arteries bifurcate to Internal and External Carotid arteries; Internal Carotid arteries supply 80% of brain; 15% of strokes are associated with stenosis (narrowing) of Internal Carotid artery at or near bifurcation. II. GROSS ANATOMY OF BLOOD SUPPLY OF SPINAL CORD A. Arterial supply 1. Anterior Spinal artery - single artery formed from branches of both Vertebral arteries; courses on anterior surface of cord. 2. Posterior Spinal arteries - paired arteries dorsolateral to spinal cord; arise (75%) from Posterior Inferior Cerebellar arteries (branch of Vertebral Artery) or directly from Vertebral arteries (25%). 3. Radicular (root) arteries - Most of blood supply to spinal cord is provided by Radicular (root) arteries; most these arteries arise from the Aorta and enter the spinal canal through Intervertebral foramina; one particularly large artery (Great Radicular Artery of Adamkiewicz, usually unpaired) arises from T9-T12 and provides major blood supply to lumbar and sacral spinal cord. Clinical Note: Obstruction of Radicular Artery (of Adamkiewicz) - Can occur during clamping for heart surgery or by a dissecting Aortic aneurysm; causes infarction (tissue death in spinal cord) similar to an Anterior Spinal Artery syndrome (symptoms include paraplegia (Corticospinal tracts, bilateral voluntary paralysis of legs and lower body), loss of pain and temperature sense (Spinothalamc tract, loss of sphincter control) with sparing of vibration and position sense (Dorsal Columns, sensory).

In the present study, over 10,000 primary spermatocytes and round spermatid cells were successfully isolated by LCM. Using the cDNAs from primary spermatocytes and round spermatids, SSH cDNAs library of primary spermatocyte-specific was constructed. The average insert size of the cDNA isolated from 75 randomly picked white clones was 500 bp, ranging from 250 bp to 1.7 kb. Using the dot-blot method, a total of 421 clones were examined, resulting in the identification of 390 positive clones emitting strong signals.

  • Latin Language and Medical Terminology
    ODESSA NATIONAL MEDICAL UNIVERSITY Department of foreign languages Latin Language and medical terminology TextbookONMedU for 1st year students of medicine and dentistry Odessa 2018 Authors: Liubov Netrebchuk, Tamara Skuratova, Liubov Morar, Anastasiya Tsiba, Yelena Chaika ONMedU This manual is meant for foreign students studying the course “Latin and Medical Terminology” at Medical Faculty and Dentistry Faculty (the language of instruction: English). 3 Preface Textbook “Latin and Medical Terminology” is designed to be a comprehensive textbook covering the entire curriculum for medical students in this subject. The course “Latin and Medical Terminology” is a two-semester course that introduces students to the Latin and Greek medical terms that are commonly used in Medicine. The aim of the two-semester course is to achieve an active command of basic grammatical phenomena and rules with a special stress on the system of the language and on the specific character of medical terminology and promote further work with it. The textbook consists of three basic parts: 1. Anatomical Terminology: The primary rank is for anatomical nomenclature whose international version remains Latin in the full extent. Anatomical nomenclature is produced on base of the Latin language. Latin as a dead language does not develop and does not belong to any country or nation. It has a number of advantages that classical languages offer, its constancy, international character and neutrality. 2. Clinical Terminology: Clinical terminology represents a very interesting part of the Latin language. Many clinical terms came to English from Latin and people are used to their meanings and do not consider about their origin.
