Recurrent Interosseous Artery

	Recurrent Interosseous Artery The interosseous recurrent artery (or recurrent interosseous artery) is an artery of the forearm which arises from the posterior interosseous artery near its origin. It ascends to the interval between the lateral epicondyle and olecranon, on or through the fibers of the supinator In human anatomy, the supinator is a broad muscle in the posterior compartment of the forearm, curved around the upper third of the radius. Its function is to supinate the forearm. Structure Supinator consists of two planes of fibers, between whic ... but beneath the anconeus. It anastomoses with the middle collateral artery.

	Posterior Interosseous Artery The posterior interosseous artery (dorsal interosseous artery) is an artery of the forearm. It is a branch of the common interosseous artery, which is a branch of the ulnar artery. Structure The posterior interosseous artery passes backward between the oblique cord and the upper border of the interosseous membrane. It appears between the contiguous borders of supinator muscle and the abductor pollicis longus muscle, and runs down the back of the forearm between the superficial and deep layers of muscles, to both of which it distributes branches. Where it lies on abductor pollicis longus muscle and the extensor pollicis brevis muscle, it is accompanied by the dorsal interosseous nerve. At the lower part of the forearm it anastomoses with the termination of the volar interosseous artery, and with the dorsal carpal network. Branches Near its origin, it gives off the interosseous recurrent artery. This ascends to the interval between the lateral epicondyle and olecranon, ...

	Lateral Epicondyle Of The Humerus The lateral epicondyle of the humerus is a large, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow joint, and to a tendon common to the origin of the supinator and some of the extensor muscles. Specifically, these extensor muscles include the anconeus muscle, the supinator, extensor carpi radialis brevis, extensor digitorum, extensor digiti minimi, and extensor carpi ulnaris. In birds, where the arm is somewhat rotated compared to other tetrapods, it is termed dorsal epicondyle of the humerus. In comparative anatomy, the term ''ectepicondyle'' is sometimes used. A common injury associated with the lateral epicondyle of the humerus is lateral epicondylitis also known as tennis elbow. Repetitive overuse of the forearm, as seen in tennis or other sports, can result in inflammation of "the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Olecranon The olecranon (, ), is a large, thick, curved bony eminence of the ulna, a long bone in the forearm that projects behind the elbow. It forms the most pointed portion of the elbow and is opposite to the cubital fossa or elbow pit. The olecranon serves as a lever for the extensor muscles that straighten the elbow joint. Structure The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. When the hand faces forward (supination) the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the forearm. Its base is contracted where it joins the body and the narrowest part of the upper end of the ulna. Its posterior surface, directed backward, is triangular, smooth, subcutaneous, and covered by a bursa. Its superior surface is of quadrilateral form, marked behind by a rough impression for the insertion of the Tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Supinator In human anatomy, the supinator is a broad muscle in the posterior compartment of the forearm, curved around the upper third of the radius. Its function is to supinate the forearm. Structure Supinator consists of two planes of fibers, between which the deep branch of the radial nerve ls. The two planes arise in common — the superficial one by tendinous (the initial portion of the muscle is actually just tendon) and the deeper by muscular fibers —''Gray's Anatomy'' (1918), see infobox from the supinator crest of the ulna, the lateral epicondyle of humerus, the radial collateral ligament, and the annular radial ligament. The superficial fibers (''pars superficialis'') surround the upper part of the radius, and are inserted into the lateral edge of the radial tuberosity and the oblique line of the radius, as low down as the insertion of the pronator teres. The upper fibers (''pars profunda'') of the deeper plane form a sling-like fasciculus, which encircles the nec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Anconeus 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 innervat ...

	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 ...
