Ulnar nerve comes off the medial cord, travels posterior medially down the arm and goes through the cubital tunnel. Does not do anything in arm, passes down the ulnar side of the arm, innervates the FDP and FCU, continues down to the hand under the palmer carpal ligament and over the flexor retinaculum travels between the pisiform and hook of hamate under pisohamate ligament, feeds 1/2 of 4th and 5th digits down plamer side and dorsal sides.
