axillary nerve innervates what muscles
The axillary nerve is derived from the posterior cord. The axillary nerve leaves the brachial plexus at the lower border of the subscapularis muscle and continues along the inferior and posterior surface of the axillary artery as the radial nerve.The axillary nerve serves as motor innervation to the deltoid and teres minor muscles, as seen in the image below.he ventral rami of C5 and C6 unite to form the upper trunk. The suprascapular nerve and the nerve to the subclavius arise from the upper trunk. The suprascapular nerve contributes sensory fibers to the shoulder joint and provides motor innervation to the supraspinatus and infraspinatus muscles.
