it runs _______ and then into the _______ part of the forearm
runs posterior to the medial epicondyle and then into the anterior of the forearm
from the elbow is supplies the:
flexor carpi ulnaris
flexor digitorium profundus (medial/ulnar)
it passes ______ those 2 muscles
between the flexor carpi ulnaris and FDP medial
it then branches into:
the Palmar branch and
dorsal branch
The Palmar branch supplies:

the Dorsal Branch supplies:
the skin on the dorsomedial side of wrist and hand

it continues to the wrist and enters:
superficial to flexor retinaculum and then through the hand
it immediately branches into:
Deep Ulnar
Superfifical

via Canal of Guyon
the Deep Ulnar supplies:
the hypothenar muscles and the
central compartment

Opponens digiti minimi
the Central Compartment muscles are:
4 dorsal interossei

Adductor Pollicis
medial 2 lumbericals
The Superficial nerve supplies:
