Regional anatomy

Upper extremity (anterior view) Ever wondered what the differences are between us humans and animals regarding the upper limb? One of them is certainly our ability to high five each other when we ace our anatomy exam. Of course, there are many more functions and This topic page will briefly discuss the upper extremity anatomy in order to introduce you to the main Key facts about the upper extremity Shoulder Glenohumeral joint: humerus, scapula, clavicle Muscles: - Superficial: deltoid, trapezius - Deep: Supraspinatus, Infraspinatus, Teres minor, Subscapularis (rotator cuff) muscles Mnemonic: Rotator cuff SITS on the shoulder Arm Bones: humerus Nerves: they all originate from the brachial plexus Arteries: branches of the brachial artery Muscles: - Anterior compartment: coracobrachialis, brachialis, biceps brachii muscles - Posterior compartment: triceps brachii Elbow Bones: humerus, radius, ulna Movements: flexion, extension, pronation, supination Forearm Bones: radius, ulna Nerves: radial, ulnar, median nerves Arteries: branches of the radial and ulnar arteries Muscles: - Anterior compartment: superficial, deep layers - Posterior compartment: superficial, deep layers Hand Bones: scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate, metacarpals (5), phalanges (proximal, middle, distal) Nerves: radial, ulnar, median nerves Arteries: terminal branches of the radial and ulnar arteries Muscles: thenar, hypothenar, metacarpal muscle groups Glenohumer...

Overview of the thorax (anterior view) More than likely you have experienced the sensation of your The chest, properly called the thorax, is the superior part of the trunk located between the • Thoracic wall • Several cavities • Neurovasculature and lymphatics • Internal organs • Breasts On this page, we’ll briefly take a look at each of the above components and how they fit together to form the thorax. Key facts about the thorax Thoracic wall Openings: superior and inferior thoracic apertures Skeleton: sternum, twelve pairs of ribs, twelve thoracic vertebrae Joints: intervertebral discs, costovertebral, joint of head of rib, sternocostal, sternoclavicular, costochondral, Intercostal spaces: intercostal vein, artery, nerve Muscles: intercostal muscles, (external, internal, innermost), transversus thoracis, subcostals, levatores costarum, serratus posterior superior, serratus posterior inferior muscles Thoracic cavity The mediastinum is located centrally and bordered by two pleural cavities laterally. The mediastinum consists of superior and inferior mediastinal cavities. The inferior mediastinal cavity is comprised of anterior, middle and posterior compartments. Neurovasculature Arterial: the three largest thoracic arteries (brachiocephalic trunk, left common carotid artery, left subclavian artery) originate from the thoracic aorta Venous: the major thoracic veins (superior vena cava, azygos venous system, accessory hemiazygos vein, pulmonary veins, esophageal ...

A course in the In this course we will be exploring the basics of regional anatomy, and building a foundational understanding of the anatomical lexicon. This course has been divided into four lessons, each taking up to thirty minutes each. You will find a Learning Summary Sidebar on the right side of each lesson. This sidebar contains useful information about prerequisites, estimated time requirements, method of assessment and level of the course. At the end of each lesson there will be a quiz to test your knowledge. This course is designed for students without prior learning in regional anatomy. If you have a strong foundation in regional anatomy you may not find this course useful. Lesson List [ | ] An introduction to the anatomical position of the human body An introduction to the planes of the human body An introduction to the terms of relationship and comparison in the human body An introduction to the movements of the human body An introduction to the facial compartments and potential spaces of the human body An introduction to the regions of the human body An introduction to the systems of the human body relating to regional anatomy

Learning Objectives By the end of this section, you will be able to: • Use appropriate anatomical terminology to identify key body structures, body regions, and directions in the body • Demonstrate the anatomical position • Describe the human body using directional and regional terms • Identify three planes most commonly used in the study of anatomy • Distinguish between major body cavities Anatomists and health care providers use terminology that can be bewildering to the uninitiated; however, the purpose of this language is not to confuse, but rather to increase precision and reduce medical errors. For example, is a scar “above the wrist” located on the forearm two or three inches away from the hand? Or is it at the base of the hand? Is it on the palm-side or back-side? By using precise anatomical terminology, we eliminate ambiguity. For example, you might say a scar “on the anterior antebrachium 3 inches proximal to the carpus”. Anatomical terms are derived from ancient Greek and Latin words. Because these languages are no longer used in everyday conversation, the meaning of their words do not change. Anatomical terms are made up of roots, prefixes, and suffixes. The root of a term often refers to an organ, tissue, or condition, whereas the prefix or suffix often describes the root. For example, in the disorder hypertension, the prefix “hyper-” means “high” or “over,” and the root word “tension” refers to pressure, so the word “hypertension” ...

Learning Objectives • Demonstrate the anatomical position • Describe the human body using directional and regional terms • Identify three planes most commonly used in the study of anatomy • Distinguish between the posterior (dorsal) and the anterior (ventral) body cavities, identifying their subdivisions and representative organs found in each • Describe serous membrane and explain its function Anatomists and health care providers use terminology that can be bewildering to the uninitiated.

These advances were made possible by the Anatomical Scientific names for the parts and structures of the human body are usually in Latin; for example, the name musculus biceps brachii denotes the By the end of the 19th century the confusion caused by the enormous number of names had become intolerable. Medical dictionaries sometimes listed as many as 20 synonyms for one name, and more than 50,000 names were in use throughout Europe. In 1887 the German Anatomical Society undertook the task of standardizing the nomenclature, and, with the help of other national anatomical societ...

Human anatomy is the study of the structure of the human body . Anatomical terms allow health care professionals to accurately communicate to others which part of the body may be affected by disorder or a disease Terms are defined in reference to a theoretical person who is standing in what is called anatomical position (see figure below): both feet pointing forwards, arms down to the side with palms forward (thumbs pointed away from the body). The positions of the arms and legs have important implications for directional terms. In the anatomical position, the head is upright and facing forward. In men, the penis is considered to be erect in the anatomical position e.g. the dorsal surface of the penis is actually the anterior (front-facing) surface in the flaccid state. Ultimately communicating using anatomical terms makes it easy to communicate description of body areas regardless of the individual’s position. For example, suppose a doctor was trying to describe an area of the body to another physician on a patient who is lying face down? Descriptions would be based on anatomical position to make things simpler and to avoid any confusion. Directional Terms For the most part, directional terms are grouped in pairs of opposites based on the standard anatomical position. • Superior and Inferior– Superior means above, inferior means below. E.g. The elbow is superior (above) to the hand. The foot is inferior (below) to the knee. • Anterior and Posterior– Anterior means toward ...
