<prompt> All are true about ulnar nerve except:Root value C8TIPass through cubital tunnelSupply flexor digitorum superficialisSupply flexor carpi ulnaris  <response>: Ans. c. Supply flexor digitorum superficialis Nerve course:Root value of ulnar nerve is C7, C8 6 T1.Ulnar nerve C8, T1 arises from the medial cord of the brachial plexus descends in the interval bw the axillary aery veinAt elbow, ulnar nerve passes behind the medial epicondyleThe cubital tunnel is a channel which allows the ulnar nerve to travel over the elbowVarious branches of ulnar nerve are :?In arm : No branch.In forearm : There are following branches :?Muscular : In proximal pa of forearm it supplies flexor carpi ulnaris and medial half of flexor digitorumprofundus.Cutaneous : There are two cutaneous branches in forearm:-Superficial terminal branch : It supplies palmaris brevis and skin of palmar surface of medial 112 fingers.Palmar cutaneous branch : Supplies skin over the hypothenar eminence.Dorsal posterior cutaneous branch : Supplies skin over medial 13 of dorsum of hand and dorsal surface of medial 112 fingers.In hand : Ulnar nerve enters the palm by passing superficial to flexor retinaculum and divides into two terminal branches :?Deep terminal branch : It supplies adductor pollicis, all interossei, medial two 3rd 4thlumbricals and all hypothenar muscles except palmaris brevis i.e. abductor digitiminimi, flexor digitiminimi, opponensdigitiminimi.
