  • Annual Meeting in Tulsa (Hosted by Elmus Beale) on June 11-15, 2019, We Were All Energized
    37th ANNUAL Virtual Meeting 2020 June 15-19 President’s Report June 15-19, 2020 Virtual Meeting #AACA Strong Due to the unprecedented COVID-19 pandemic, our 2020 annual AACA meeting in June 15-19 at Weill Cornell in New York City has been canceled. While this is disappointing on many levels, it was an obvious decision (a no brainer for this neurosurgeon) given the current situation and the need to be safe. These past few weeks have been stressful and uncertain for our society, but for all of us personally, professionally and collectively. Through adversity comes opportunity: how we choose to react to this challenge will determine our future. Coming away from the 36th Annual meeting in Tulsa (hosted by Elmus Beale) on June 11-15, 2019, we were all energized. An informative inaugural newsletter edited by Mohammed Khalil was launched in the summer. In the fall, Christina Lewis hosted a successful regional meeting (Augmented Approaches for Incorporating Clinical Anatomy into Education, Research, and Informed Therapeutic Management) with an excellent faculty and nearly 50 attendees at Samuel Merritt University in Oakland, CA. The midyear council meeting was coordinated to overlap with that regional meeting to show solidarity. During the following months, plans for the 2020 New York meeting were well in motion. COVID-19 then surfaced: first with its ripple effect and then its storm. Other societies’ meetings - including AAA and EB – were canceled and outreach to them was extended for them to attend our meeting later in the year. Unfortunately, we subsequently had to cancel the plans for NY.

Byram, Ph.D., Indiana University School of Medicine Learning Objectives • Identify anatomical position and anatomical planes, and use directional terms to describe relative positions of bones • Describe the gross structure and microstructure of bone as it relates to bone function • Describe types of bone formation and remodeling, and identify (by name) all of the bones of the human skeleton • Distinguish major bony features of the human skeleton like muscle attachment sites and passages for nerves and/or arteries and veins • Identify the bony features relevant to estimating age, sex, and ancestry in forensic and bioarchaeological contexts • Compare human and chimpanzee skeletal anatomy Anthropology is the study of people, and the skeleton is the framework of the person. So while all subdisciplines of anthropology study human behavior (culture, language, etc.) either presently or in the past, biological anthropology is the only subdiscipline that studies the human body specifically. And the fundamental core of the human (or any vertebrate) body is the skeleton. Osteology, or the study of bones, is central to biological anthropology because a solid foundation in osteology makes it possible to understand all sorts of aspects of how people have lived and evolved.

  • Anatomical Terminology, Skeletal System
    Anatomical Terminology & Skeletal System DR JAMILA EL MEDANY OBJECTIVES At the end of the lecture, students should be able to: Define the word “Anatomy” Enumerate the different anatomical fields Describe the anatomical position Describe different anatomical terms of position & movements as well different anatomical planes Classify bones according to shape, structure & development Enumerate bones of axial & appendicular skeleton ANATOMY (to Cut) The science which deals with the study of the structure and shape of the body & body parts, and their relationships to one another It is divided into: Gross Anatomy: Study of human body with naked eye Microscopic Anatomy (Histology): Study of fine structures (cells & tissues) of the human body with the help of microscope Developmental Anatomy ( Embryology) Radiological Anatomy Cross-sectional Anatomy Applied Anatomy Surgical Anatomy The Language of Anatomy (Anatomical Terminology) To prevent misunderstanding, a special set of terms are used to describe the identification and location of body structures To accurately describe body parts, the body is in a standard position called the Anatomical Position, in which: Body is erect Arms hanging by the side Palms facing forward Feet are parallel PLANES OF THE BODY To do a Section (cut) through the body wall or an organ, it is made along an Imaginary Line (PLANE). The body has Three Imaginary Planes (sections ) that lie at right angles to one another (in the anatomical position). 1. Median sagittal. 2. Coronal. 3.Horizontal (Transverse). MEDIAN (MidSagittal )PLANE It is a Vertical plane. It passes through the Center (Midline) of the body. It divides the body into Right and Left halves.

  • Anatomical Terminology
    Anatomical Terminology Because the unit we are currently studying involves the human body, it is necessary for you to familiarize yourself with some basic anatomical terminology as it relates to the human body. Directional Terms Directional terms describe the positions of structures relative to other structures or locations in the body. Superior or cranial - toward the head end of the body; upper (example, the hand is part of the superior extremity). Inferior or caudal - away from the head; lower (example, the foot is part of the inferior extremity). Anterior or ventral - front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal - back (example, the shoulder blades are located on the posterior side of the body). Medial - toward the midline of the body (example, the middle toe is located at the medial side of the foot). Lateral - away from the midline of the body (example, the little toe is located at the lateral side of the foot). Proximal - toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone). Distal - away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm). Planes of the Body Coronal Plane (Frontal Plane) - A vertical plane running from side to side; divides the body or any of its parts into anterior and posterior portions. Sagittal Plane (Lateral Plane) - A vertical plane running from front to back; divides the body or any of its parts into right and left sides.

  • The Study of Human Anatomy
    The Study of Human Anatomy Chapter 1 Chapter Outline An overview of Anatomy: a) Define anatomy and physiology b) learn subdivisions of anatomy c) methods of study d) organ systems e) levels of structural organization Gross Anatomy: anatomical position; anatomical terminology, body cavities, 9 regions and 4 quadrants of abdomen, Microscopic Anatomy: preparation and examination of slides with a light microscope An Overview of Anatomy Anatomy is the study of Structure or form of body and body parts and their relationships to one another. (anatome = dissection). Morphology Morphe = form, logos = study Physiology is the study of Function of body and body parts. Structure supports function. For example, the cornea of eye is transparent and curved. It allows light to pass through and focuses it as image. Anatomy Major subdivisions of anatomy Gross Anatomy is the study of body surface, regions, and sections. It studies organs and their relationship to one another. Microscopic Anatomy studies the cells and tissues. Cytology is the study of cells and Histology is the study of tissues. Systemic and Regional Anatomy Methods of study Inspection is to look keenly on body surface or parts. Nails, eyes, tongue, injury marks. Palpation means feeling a structure with hands. Pulse. Auscultation means listening to natural sound made by the body. Heart or lung sounds with stethoscope. Dissection is cutting open the internal organs Exploratory Surgery of past is now replaced by imaging techniques – radiography (X-rays), sonography (Ultrasound scanning), CT scan and MRI X-rays are invasive, can cause mutations; MRI is noninvasive. Levels of Organization Smaller entities interact with one another and form bigger entities that can perform additional functions.

  • Anatomical Terminology Review
    Anatomical Terminology Review Caudal Anterior Superior Deep Lateral Dorsal Proximal Ventral Coronal Inferior Cranial Medial Superficial Distal Transverse Median Posterior Sagittal Anatomical Terminology Review Anterior Coronal Caudal Median Cranial Sagittal Deep Transvers Distal e Dorsal Inferior Lateral Medial Posterior Proximal Sagittal Superior Superficial Transverse Ventral Having an understanding of anatomical terminology is critical to being able to describe body locations in appropriate detail. This will help you throughout the year. Use your background knowledge to figure out the meanings of the terms. Anatomical Terminology POGIL 1. Think of the meaning of the word superior. “The General is my superior officer.” What does the anatomical term superior mean? 2. What part of the body is the cranium? Does this fit with your answer for number 1? 3. Caudal is an antonym of the word cranial, but rarely used for humans. What might caudal mean? 4. Think of the meaning of the word inferior and then write a sentence using that anatomical term. What two terms are the opposite of inferior? 5. How do caudal and inferior differ? How do superior and cranial differ? Anatomical Terminology POGIL Sagittal The previously defined terms are Median used to indicate specific parts of Coronal the body. Sagittal, median, Transverse coronal, and transverse are different because they are used to describe cuts made on different planes. Now that you know the meaning of several anatomical terms, Let’s practice. Shape your Play-doh into a gingerbread man shape. 6. Place a toothpick into the man superior to his eye. 7. Place another toothpick just inferior to the nose.

Chmielewski Division of Anatomy, Department of Human Morphology and Embryology, Faculty of Medicine, Wroclaw Medical University, Wroclaw, Poland [Received: 12 October 2019; Accepted: 17 November 2019; Early publication date: 3 December 2019] In 2019, the updated and extended version of Terminologia Anatomica was published by the Federative International Programme for Anatomical Terminology (FIPAT). This new edition uses more precise and adequate anatomical names compared to its predecessors. Nevertheless, numerous terms have been modified, which poses a challenge to those who prefer traditional anatomical names, i.e. medical students, teachers, clinicians and their instructors. Therefore, there is a need to popularise this new edition of terminology and explain these recent changes. The anatomy of the head, including the cranium, the extracranial bones of the head, the soft parts of the face and the encephalon, poses a particular challenge for medical students but also engenders enthusiasm in those of them who are astute learners. The new version of anatomical terminology concerning the human skull (FIPAT 2019) is presented and briefly discussed in this synopsis. The aim of this article is to present, popularise and explain these interesting modifications that have recently been endorsed by the FIPAT. Based on teaching experience at the Division of Anatomy/Department of Anatomy at Wroclaw Medical University, a brief description of the human skull is given here.
