Recurrent Branch Of Median

The recurrent branch of the median nerve is a small branch of the median nerve that supplies the thenar muscles of the hand. It arises from the median nerve just proximal to the flexor retinaculum and then passes deep to the flexor retinaculum and the transverse carpal ligament. The recurrent branch of the median nerve then supplies the abductor pollicis brevis, the opponens pollicis, and the superficial head of the flexor pollicis brevis muscles.

Median

The brachial plexus is formed by the ventral rami of c5-c8-t1 spinal nerves, and lower and upper halves of c4 and t2 spinal nerves. the plexus extends toward the armpit. the ventral rami of c5 and c6 form upper trunk, the ventral ramus of c7 forms the middle trunk, and the ventral rami of c8 and t1 join to form the lower trunk of the brachial plexus. under the clavicle, the trunks reorganize to form cords (fasciculi) around the axillary artery (arteria axillaris). the lateral cord (fasciculus lateralis) is formed by the upper and middle trunk, all three trunks join to form the posterior cord (fasciculus posterior), the lower trunk continues to the medial trunk (fasciculus medialis). the nerves (containing motor and sensory fibers) to the shoulder and to the upper limb emerge from the brachial plexus.
