Origin
The nerve to pronator teres muscle originates from the median nerve in the region of the cubital fossa and contains nerve fibers from the C6 and C7 segments of the cervical spinal cord.
Course
Following its origin from the lateral and medial cords of brachial plexus, the median nerve descends distally in the arm as it crosses the brachial artery from its lateral to its medial side to reach the cubital fossa. Inside the cubital fossa, the median nerve lies medial to the brachial artery and deep to bicipital aponeurosis.
The median nerve exits the cubital fossa and descends between the two heads of the pronator teres muscle. The branch of nerve for this muscle usually originates in the region of the cubital fossa and pierces the muscle on its inferolateral side.
Branches
No named branches.
Supplied Structures
The muscular branch of median nerve to pronator teres provides motor innervation to pronator teres muscle.
