Back to “Memory Booster of Regional Anatomy (2017 Edition)”

 

Introduction

 

 

Anatomy is an old, well documented medical science; its history traces back to ancient civilizations such as Egypt, Babylon, and China. Nowadays, information on anatomy can easily be accessed either from detailed anatomy books or from various Internet sites such as Wikipedia. Regretfully, students perceive anatomy as a difficult subject because of the vast amount of contents which are overwhelming. Medical schools are continuously decreasing the number of hours anatomy is being taught, and thus inevitably contributes to the difficulty students experience when studying anatomy.

The purpose of this book is to help make regional anatomy easy to be memorized by the students who dissect cadavers. To serve this purpose, this book concentrates on accessible and easy-to-read stories rather than focusing on exhaustive details. Fittingly, this book is entitled “Memory Booster of Regional Anatomy.” This book is neither complete nor thorough to be exact. Some notes to keep in mind regarding this book are below.

First, osteology is not incorporated into the book; bone structures are not delineated. We have just included a list of essential bone structures in the prologue. In South Korea, medical school students learn osteology by themselves prior to taking anatomy classes.

Second, we also have not provided organized tables on muscles (origin, insertion, action, and innervation), because these tables would only serve the purpose of a dictionary, rather than a book that aids understanding of anatomy.

Third, we have minimized the explanation on anatomical terms. For example, the nostril, the entrance of nasal cavity, is not mentioned in this book. Even without the word, nostril, nasal cavity can be explained with little to no limitations. For similar reasons, in the sections on upper and lower limbs, explanations on cutaneous nerves are omitted. Cutaneous nerves generally have puzzling names and complicated origins to study individually.

Fourth, we try not to teach the structures that are unidentifiable in cadavers. For instance, liver segments are not listed despite their clinical significance for the reason that these segments are hardly discriminated by routine cadaver dissection.

Fifth, we have decreased our emphasis on numbers. Only meaningful numbers are introduced. An example of this case would be that despite the fact that the origins of the anterior, middle, posterior scalene muscles are the 3rd–6th, 2nd–7th, 5th–7th cervical vertebrae, respectively, the origins are introduced as simply the cervical vertebrae. We recommend readers to refer to other sources for additional details.

Sixth, eponyms that are difficult to memorize (e.g., Stenson’s duct) are omitted. It would be not late and even more beneficial for readers to familiarize themselves with these specific eponyms in clinics.

Seventh, some information, at the cost of preciseness, is altered. For instance, we have described that the lumbosacral plexus (2nd lumbar nerve to 3rd sacral nerve) to arise from the lumbosacral enlargement. However, to be exact, 11th thoracic nerve to 1st sacral nerve arise from the lumbosacral enlargement. We have made this adjustment to make the information simpler and easier for the readers in context.

Eighth, clinical anatomy is not dealt with in this book. Diseases such as carpal tunnel syndrome and atrial septal defect are not discussed. We have chosen to concentrate on anatomy itself and its supportive embryology, and less on clinical knowledge.

Ninth, the illustrations in this book are very simple. For example, muscles are drawn as arrows, only indicating insertions and origins. These drawings are effective in explaining the morphology and function of the structures that are discussed. Readers can easily redraw our illustrations which would be helpful for memorization. However, comparing our schematic figures to the realistic anatomy atlas and dissected cadaver is mandatory, to gain an accurate insight.

This book contains plenty of tips (mnemonics) which would help the readers memorize the anatomy terms. A third of the tips are made by others to whom the authors are grateful. Among the tips, readers may pick their favorites.

Comics drawn by the first author are included in order to help anatomy feel more approachable. The full episodes of the comics are in the published book (Min Suk CHUNG: Anatomy Comic Strips. Hanmi Medical Publishing Co., 2013). The comics are also available on via the web on anatomy.co.kr. Also on the website are a dissection manual, browsing software packages for sectional anatomy, and three-dimensional models (PDF files) for stereoscopic anatomy, all of which are free. The more users benefit from those resources, the more we feel fruitful of our work.

This book is not the first work that has attempted to make anatomy enjoyable. Such credit goes to “Clinical Anatomy Made Ridiculously Simple (Stephen GOLDBERG, Hugue OUELLETTE, MedMaster, Inc., 2012).” We suggest our readers to refer to this book.

Unlike the previous publication that handles systemic anatomy, this book deals with regional anatomy in attempts to provide direct assistance in cadaver dissection. In each region (back, upper limb, etc.), anatomical structures are introduced in accordance with the suggested dissection procedure when possible. The order in which readers study different chapters of this book is not significant. The only guideline to heed to is that readers read the upper limb chapter prior to the lower limb chapter.

Here we faithfully follow the official anatomical terms, Terminologia Anatomica. However, some obvious words were omitted. For example, we use “risorius” (muscle term in Latin) instead of “risorius muscle.” Abbreviations such as III for oculomotor nerve are utilized, which are introduced in prologue. Some terms (e.g., anterior forearm muscles) have been developed for consistency.

Plenty of drawings were created on Adobe Illustrator by the students in Ajou University School of Medicine (Yeon Ah PARK, Je Hwi YUN), Ga Eun LEE, Hae Gwon JANG, Yoon Ik HWANG, and Beom Jo CHUNG. Other students in Ajou University School of Medicine (including Shiho LEE, Young Hoon SONG, and Byung Jin CHOI) have suggested major and minor corrections. Respectable Korean anatomists (Ki Seok KOH, Chang Seok OH, Jin Seo PARK, Jae-Ho LEE) have assisted the manuscript revision. A friendly clinician (Eun Seo KIM) gave a hand with favors. English assistance was provided from students in Ajou University School of Medicine (Yeonju HONG, Jisoo KIM, Yoon Sub KIM, and Jimin LEE) and Jiyoon KIM.

All works for this book were supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (grant number 2014R1A1A2053405).

We distribute this book as a portable document format (PDF) file regardless of commercial return. Following is our copyleft policies: 1. The PDF file is downloadable on the homepage (anatomy.co.kr) without charge or registration. This electronic book can be printed to make a paper book as the users prefer. 2. The clients are allowed even to upload the PDF file or its figures (including comics) on the web and so on in the case of non-commercial purposes. The same policy applies to other comics and Visible Korean products on the identical site (anatomy.co.kr). However, when utilizing the figures for public, we courteously ask that the source “Memory Booster of Regional Anatomy (by MS CHUNG, BS CHUNG)” or the homepage “anatomy.co.kr” be inscribed.

We will gladly receive any comments and suggestions on this book by e-mail (dissect@ajou.ac.kr) of Min Suk Chung, the corresponding author. We will take these feedbacks and reflect them in the next version of the book. This book will be annually revised, as we strive to step closer to a perfect book.

We wish that “Memory Booster of Regional Anatomy” will serve as an actually helpful resource to students encountering anatomy. Anatomy should be comprehended, not blindly memorized. Enjoying anatomy is better than suffering from anatomy.
