establishes with the median nerve, a loop is formed through which 

 the axillary artery passes. The musculocutaneous nerve pierces 

 the insertion of the coracobrachial muscle along with the anterior 

 circumflex artery, supplies the muscle in passing, and ends in the 

 biceps. It also furnishes a cranial pectoral nerve to the pectoral

N. MEDIANUS. — The median is generally the largest nerve derived 

 from the brachial plexus, though the radial may be as large or possibly 

 larger. After its connection with the musculocutaneous, the median 

 passes down the arm along the anterior border of the axillary and 

 brachial arteries, and enters the forearm in company with the median 

 artery.
