* '''Caudal circumflex humeral vessels'''

The '''thoracodorsal and circumflex arteries''' are branches of the '''subscapular artery'''.  The '''cranial circumflex humeral artery''' runs deep to the coracobrachialis to supply the [[Muscles of the Elbow - Horse Anatomy#Flexors|''biceps'']]; its corresponding satellite vein can cross the coracobrachialis on either surface.  The '''thoracodorsal vein''' gives rise to the '''superficial thoracic vein''', which passes caudally to drain the ventral part of the trunk.

The '''brachial vessels''' give rise to deep brachial vessels, which supply the [[Muscles - Horse Anatomy#Muscles of the Elbow|''triceps'']].  More distally, brachial vessels form '''bicipital vessels''' to the [[Muscles - Horse Anatomy#Muscles of the Elbow|''biceps'']].  The next branches from the brachial vessels are the '''transverse cubital vessels''', which pass deep to the [[Muscles - Horse Anatomy#Muscles of the Elbow|''biceps'']].  The '''collateral ulnar vessels''' arise from the caudal surface of the brachial vessels, following the path of the ulnar nerve.  The final branches are the '''common interosseous vessels''', which pass through the interosseous space to continue as the '''cranial interosseous vessels'''.
