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
Suprascapular artery is a small and flexuous vessel arising from the upper face of the brachial artery about the middle of its extra thoracic course. It ascends and dips in the space between the supraspinatus and subscapularis in company with its satellite vein and suprascapular nerve and divides to supply the subscapularis, supraspinatus, brachiocephalicus and
Suprascapular artery External thoracic artery Subscapular artery The thoraco-dorsal artery The posterior circumflex artery of the humerus The circumflex artery of the scapula Anterior circumflex artery of the humerus Deep brachial artery Collateral ulnar artery Collateral radial artery Median artery Collateral Branches A long muscular branch Common interosseous artery The dorsal interosseous artery The terminal
Inferior cervical artery of Brachial artery arises from the brachial artery at varying levels usually just before it winds round the first rib from its dorsal face. It is directed downwards and forward and to the deep face of the brachiocephalicus between it and the omotransversarius. It supplies branches to the posterior cervical lymph glands,
Internal thoracic artery of Brachial artery is a large vessel, which arises from the ventral face of the brachial artery opposite the first rib. It passes downwards and backwards within the thoracic cavity and terminates into the musculophrenic and anterior abdominal arteries. Collateral branches of Internal thoracic artery At each intercostal space it gives off
