"first (suprapectoral) part: from its origin at the lateral edge of the first rib to the superior border of pectoralis minor"
"second (retropectoral) part: posterior to pectoralis minor"
"third (infrapectoral) part: from the inferior border of pectoralis minor to the inferior border of teres major"
"2nd part: of the axillary artery, the posterior, lateral and medial cords embrace the artery as per their names"
"Branches from the axillary artery are highly variable 1,3 and often include the subscapular artery and posterior circumflex humeral artery 3, but also other branches:"
Expected headings
"Parts"
"thoracoacromial artery: runs over pectoralis minor to pierce the clavipectoral fascia and supply the clavicle, deltoid, acromion and pectoralis muscles via its four terminal branches"
"2nd part: of the axillary artery, the posterior, lateral and medial cords embrace the artery as per their names"
"alar thoracic artery: supplies the fat, skin and lymph nodes of the axilla 4"
"subscapular artery: the largest branch of the axillary artery, travels along the posterior wall of the axilla; distally, it divides into the thoracodorsal artery, giving branches to the serratus anterior, and into the circumflex scapular artery, which contributes to the scapular anastomosis; the thoracodorsal artery then runs with the thoracodorsal nerve from the posterior cord to enter and supply the anterior edge of latissimus dorsi"
"subscapular artery: the largest branch of the axillary artery, travels along the posterior wall of the axilla; distally, it divides into the thoracodorsal artery, giving branches to the serratus anterior, and into the circumflex scapular artery, which contributes to the scapular anastomosis; the thoracodorsal artery then runs with the thoracodorsal nerve from the posterior cord to enter and supply the anterior edge of latissimus dorsi"
"posterior humeral circumflex artery: passes through the posterior wall of the axilla with the axillary nerve to supply the deltoid; it is the dominant supply for the humeral head and also supplies triceps brachii and the glenohumeral joint 2,5"
"1st part: the lateral and posterior cords lie superolateral, whereas the medial cord lies posteriorly; a loop connecting the medial and lateral pectoral nerves also lies anterior to the axillary artery"
