Anconæus
The anconeus muscle (or anconaeus/anconæus) is a small muscle on the posterior aspect of the elbow joint. Some consider anconeus to be a continuation of the triceps brachii muscle. Some sources consider it to be part of the posterior compartment of the arm, while others consider it part of the posterior compartment of the forearm. The anconeus muscle can easily be palpated just lateral to the olecranon process of the ulna. Structure Anconeus originates on the posterior surface of the lateral epicondyle of the humerus and inserts distally on the superior posterior surface of the ulna and the lateral aspect of the olecranon. Innervation Anconeus is innervated by a branch of the radial nerve (cervical roots 7 and 8) from the posterior cord of the brachial plexus called the nerve to the anconeus. The somatomotor portion of radial nerve innervating anconeus bifurcates from the main branch in the radial groove of the humerus. This innervation pattern follows the rules of innervation ...

Human Anatomical Terms
Anatomical terminology is a specialized system of terms used by anatomists, zoologists, and health professionals, such as doctors, surgeons, and pharmacists, to describe the structures and functions of the body. This terminology incorporates a range of unique terms, prefixes, and suffixes derived primarily from Ancient Greek and Latin. While these terms can be challenging for those unfamiliar with them, they provide a level of precision that reduces ambiguity and minimizes the risk of errors. Because anatomical terminology is not commonly used in everyday language, its meanings are less likely to evolve or be misinterpreted. For example, everyday language can lead to confusion in descriptions: the phrase "a scar above the wrist" could refer to a location several inches away from the hand, possibly on the forearm, or it could be at the base of the hand, either on the palm or dorsal (back) side. By using precise anatomical terms, such as "proximal," "distal," "palmar," or "do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nomina Anatomica
''Nomina Anatomica'' (''NA'') was the international standard on human anatomic terminology from 1895 until it was replaced by '' Terminologia Anatomica'' in 1998. In the late nineteenth century some 30,000 terms for various body parts were in use. The same structures were described by different names, depending (among other things) on the anatomist's school and national tradition. Vernacular translations of Latin and Greek, as well as various eponymous terms, were barriers to effective international communication. There was disagreement and confusion among anatomists regarding anatomical terminology. Editions The first and last entries in the following table are not NA editions, but they are included for the sake of continuity. Although these early editions were authorized by different bodies, they are sometimes considered part of the same series. Before these codes of terminology, approved at anatomists congresses, the usage of anatomical terms was based on authoritative works ...

Heterotopic Ossification
Heterotopic ossification (HO) is the process by which bone tissue forms Heterotopia (medicine), outside of the skeleton in muscles and soft tissue. Symptoms In traumatic heterotopic ossification (traumatic myositis ossificans), the patient may complain of a warm, tender, firm swelling in a muscle and decreased range of motion in the joint served by the muscle involved. There is often a history of a blow or other trauma to the area a few weeks to a few months earlier. Patients with traumatic neurological injuries, severe neurologic disorders or severe burns who develop heterotopic ossification experience limitation of motion in the areas affected. Causes Heterotopic ossification of varying severity can be caused by surgery or trauma to the hips and legs. About every third patient who has total hip arthroplasty (joint replacement) or a severe fracture of the long bones of the lower leg will develop heterotopic ossification, but is uncommonly symptomatic. Between 50% and 90% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrist
In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; "The wrist contains eight bones, roughly aligned in two rows, known as the carpal bones." (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as ''wrist joints''. "With the large number of bones composing the wrist (ulna, radius, eight carpas, and five metacarpals), it makes sense that there are many, many joints that make up the structure known as the wrist." This region also includes the carpal tunnel, the anatomical snuff box, bracelet lines, the flexor retinaculum, and the extensor retinaculum. As a consequence of these various definitions, f ...

Profunda Brachii Artery
The deep artery of arm (also known as deep brachial artery) is a large artery of the arm which arises from the brachial artery. It descends in the arm before ending by anastomosing with the radial recurrent artery. Structure Origin The deep artery of arm arises from the posterolateral aspect of the brachial artery, just below the lower border of the teres major. Course It follows closely the radial nerve, running at first backward between the long and medial heads of the triceps brachii, then along the groove for the radial nerve (the radial sulcus), where it is covered by the lateral head of the triceps brachii, to the lateral side of the arm; there it pierces the lateral intermuscular septum, and, descending between the brachioradialis and the brachialis to the front of the lateral epicondyle of the humerus, ends by anastomosing with the radial recurrent artery. Branches and anastomoses It gives branches to the deltoid muscle (which, however, primarily is supplied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Collateral Artery
The medial collateral artery (also known as the middle collateral artery) is a branch of profunda brachii artery that descends in the middle head of the triceps brachii and assists in forming the anastomosis with the interosseous recurrent artery above the olecranon of the ulna near the elbow. See also * radial collateral artery * superior ulnar collateral artery * inferior ulnar collateral artery The inferior ulnar collateral artery (anastomotica magna artery) is an artery in the arm. It arises about 5 cm. above the elbow from the brachial artery. Course It passes medialward upon the brachialis, and piercing the medial intermuscular s ...

Radius (bone)
The radius or radial bone (: radii or radiuses) is one of the two large bones of the forearm, the other being the ulna. It extends from the Anatomical terms of location, lateral side of the Elbow-joint, elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is longer than the radius, but the radius is thicker. The radius is a long bone, Prism (geometry), prism-shaped and slightly curved longitudinally. The radius is part of two joint (anatomy), joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone. The corresponding bone in the human leg, lower leg is the tibia. Structure The long narrow medullary cavity is enclosed in a strong wall of compact bone. It is thickest along the interosseous border and thinnest at the extremities, same over the cup-shaped articular surface (fovea) of the head. The tra ...

Olecranon Fossa
The olecranon fossa is a deep triangular depression on the posterior side of the humerus, superior to the trochlea. It provides space for the olecranon of the ulna during extension of the forearm. Structure The olecranon fossa is located on the posterior side of the distal humerus. The joint capsule of the elbow The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and t ... attaches to the humerus just proximal to the olecranon fossa. Function The olecranon fossa provides space for the olecranon of the ulna during extension of the forearm, from which it gets its name.

Brachial Plexus
The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four Spinal nerve#Cervical nerves, cervical nerves and first Spinal nerve#Thoracic nerves, thoracic nerve (cervical spinal nerve 5, C5, Cervical spinal nerve 6, C6, cervical spinal nerve 7, C7, cervical spinal nerve 8, C8, and thoracic spinal nerve 1, T1). This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the axilla, armpit, it supplies Afferent nerve fiber, afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand. Structure The brachial plexus is divided into five ''roots'', three ''trunks'', six ''divisions'' (three anterior and three posterior), three ''cords'', and five ''branches''. There are five "terminal" branches and numerous other "pre-terminal" or "collateral" branches, such as the subscapular nerve, the thoracodorsal nerve, and the long thoracic nerve, that leave the plexus at vari ...
