Book Description
McMinn's Color Atlas of Head and Neck Anatomy is the only large format atlas of the human head and neck, incorporating outstanding dissections, osteology, and radiographic and surface anatomy images. Bari M. Logan, Patricia Reynolds, and Ralph T. Hutchings present a "road map" reference to the structures of the head and neck, ideal for study or exam review. New dissections and double page spreads provide detailed depictions for additional and more specific areas. The more complex dissections are accompanied by explanatory artwork and all dissections are accompanied by notes and commentaries. Reference lists and dental anesthesia information are incorporated into appendices at the back of the book. All in all, this is a beautiful and thorough atlas of the whole head and neck region. "It is difficult find any fault with a book that has been so painstakingly prepared and remains so comprehensively relevant. A copy in the library for reference is not good enough - everyone should have their own!" European Journal of Orhtodontics, July 2010 Presents life-sized images of dissections and osteology to correspond with what you see in the lab or in practice. Includes radiography and surface anatomy pictures so that the content is clinically relevant. Features notes and commentaries for every dissection and orientational and explanatory artwork for those that are more complex so that you have a complete understanding of position and application. Incorporates reference lists and dental anesthesia information into appendices at the back of the book for additional resources and clinical material. Features 12 new "in-fill" dissections of single glands to serve as the definitive reference for head and neck. Presents new double page spreads on vascularity of the brain, eruption and growth of deciduous teeth, sutural bones, and the skull for more detailed depictions of these key areas. Includes new clinical photographs that reflect the current state of practice and keep you up to date.

Cross-Sectional Atlas of the Human Head
Author: Jin Seo Park
Publisher: Springer
ISBN: 9811007705
Category : Medical
Languages : en
Pages : 328
Book Description
This superb color atlas sets a new standard in neuroanatomy by presenting around 300 detailed thin-sectioned images of the human head, including the brain, with 0.1-mm intervals and a pixel size of 0.1 mm × 0.1 mm. A new reference system employed for this purpose is clearly explained, and structures are fully annotated in the horizontal, coronal, and sagittal planes. Recent advances in 7T MRI and 7T TDI have considerably enhanced imaging of the human brain, thereby impacting on both neuroscience research and clinical practice. Moreover, the information gained from initiatives involving photography of thin slices of human cadavers, such as the Visible Human Projects, Visible Korean and Chinese Visible Human, has enriched knowledge of neuroanatomy and thereby facilitated the interpretation of such ultra-high-field resolution images. The exquisite images contained within this atlas will be invaluable in providing both researchers and clinicians with important new insights.

Written by an experienced and well-respected physician and professor, this new volume, building on the previous volume, Ultrasonic Topographical and Pathotopographical Anatomy, also available from Wiley-Scrivener, presents the ultrasonic topographical and pathotopographical anatomy of the head and neck, offering further detail into these important areas for use by medical professionals. This atlas of topographic and pathotopographic human anatomy is a fundamental and practically important book designed for doctors of all specializations and students of medical schools. Here you can find almost everything that is connected with the topographic and pathotopographic human anatomy, including original graphs of logical structures of topographic anatomy and development of congenital abnormalities, topography of different areas in layers, pathotopography, computer and magnetic resonance imaging (MRI) of topographic and pathotopographic anatomy. Also you can find here new theoretical and practical sections of topographic anatomy developed by the author himself which are published for the first time. They are practically important for mastering the technique of operative interventions and denying possibility of iatrogenic complications during operations. This important new volume will be valuable to physicians, junior physicians, medical residents, lecturers in medicine, and medical students alike, either as a textbook or as a reference. It is a must-have for any physician’s library.
