Muscular Branch of Median Nerve to Flexor Digitorum Superficialis (Right)

Ramus musculi superficialis flexoris digitorum nervi mediani

The nerve to flexor digitorum superficialis muscle originates from the median nerve in the cubital fossa and contains nerve fibers from the C8 and T1 segments of the cervical and thoracic spinal cord.


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 and between the humeroulnar and radial heads of the flexor digitorum superficialis muscle, where it travels distally down the forearm in the fascia deep to the muscle. Here, the median nerve innervates the flexor digitorum superficialis in a lateral branching pattern, just proximal to where the median nerve gives off the anterior antebrachial interosseous nerve.


No named branches.
