Dorsal metacarpal artery is very small vessel (often absent), which arises from the rete carpi dorsale. It passes down the dorsal metacarpal groove and below the fetlock it is joined by the distal perforating metacarpal artery from the deep volar arch to form the volar common digital artery. This receives a communicating branch from the […]

The Ulnar artery of the brachial artery is the larger of the two terminal branches of the median artery. It descends under the flexor carpi radialis, passes through the carpal canal on the medial face of tendon of the deep flexor and is continued as the volar common digital artery. This vessel passes superficially underneath

The radial artery is the smaller of the two terminal branches of the median artery. It descends along the medio-volar border of the radius under the flexor carpi radialis, passes down subcutaneously over the posterior aspect of the carpus under the deep fascia but out side the carpal canal and is continued down as the

The Median artery of the brachial artery is the continuation of the brachial artery below the level of the medial condyle of the Humerus. It passes along the posteromedial face of the radius and divides at variable distances down the forearm into radial and ulnar arteries. Collateral branches of Median artery A long muscular branch

Collateral radial artery is a large vessel which arises from the lateral face of the brachial artery at its lower most part, runs outwards and downwards in company with the musculocutaneous branch of the median nerve under the lower part of the biceps and divides into superficial and deep branches. The former runs forwards in

Collateral ulnar artery arises from the posterior face of the brachial artery and is small. It divides into ascending and descending branches to supply caput longum, anconeus, flexor carpi ulnaris and superficial flexor of the digit. This branch corresponds to the ulnar artery of the horse and accompanies the ulnar nerve.

Deep brachial artery is a small vessel arising from the posterior face of the brachial artery about the middle of the Humerus. It passes backwards between the long and medial heads of triceps, supplies these muscles and tensor fasciae antibrachi.

ANTERIOR CIRCUMFLEX ARTERY OF THE HUMEROUS MUSCLE Anterior circumflex artery of the Humerus branch arises from the anterior face of the brachial artery at the anterior border of the lower part of teres major and finally terminates in the biceps. It supplies the biceps brachii and coracobrachialis.

Subscapular artery is a very large vessel as large as the brachial artery. It arises from the posterior face at the posterior border of the subscapularis muscle. It ascends in the space between the subscapularis and teres major along the medial face of the long head of triceps, then along the posterior border of the

External thoracic artery is a large vessel arising from the ventral face of the brachial artery at about the level of the anterior border of the first rib. It passes backwards on the deep face of the deep pectoral muscle. It gives off a number of branches to the pectoral muscles, axillary lymph gland, panniculus
