The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm.
The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. [1] ... Blood supply. The anastomosis and deep veins around the elbow-joint.
It follows closely the radial nerve, running at first backward between the long and medial [1] 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 ...
Joint anastomoses: Almost all joints receive anastomotic blood supply from more than one source. Shoulder (and circumflex humeral) Elbow (see blood supply of elbow) Hip (and circumflex iliac; see also cruciate anastomosis) Knee (and genicular arteries; see also patellar network) Ankle; Abdominal anastomoses Marginal artery of the colon; Pelvic ...

Its role in elbow extension is trivial in humans. It assists in extension of the elbow, where the triceps brachii is the principal agonist, and supports the elbow in full extension. [7] It also prevents the elbow joint capsule being pinched in the olecranon fossa during extension of the elbow. Anconeus also abducts the ulna and stabilizes the ...
Their blood supply is from the profunda brachii. The triceps brachii is a large muscle containing three heads a lateral, medial, and middle. The anconeus is a small muscle that stabilizes the elbow joint during movement.
The distal part of the upper limb between the elbow and the radiocarpal joint (wrist joint) is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand. By anatomical definitions, the bones , ligaments and skeletal muscles of the shoulder girdle , as well as the axilla between them, are considered parts of the upper ...
