 It pierces the Coracobrachialis muscle and passes obliquely between the Biceps 

 brachii and the Brachialis, to the lateral side of the arm; a little above the elbow 

 it pierces the deep fascia lateral to the tendon of the Biceps brachii and is continued 

 into the forearm as the lateral antibrachial cutaneous nerve. In its course through
