In this article we shall look at the applied anatomy of the nerve its anatomical course motor functions and cutaneous innervation. A regular x ray can be helpful if there are concerns about deformities of the bone bone spurs or other abnormal structures which could be causing irritation to the ulnar. In human anatomy the ulnar nerve is a nerve that runs near the ulna bone.
Gross anatomy origin the ulnar nerve originates as a terminal branch of the medial cord of the brachial plexus wit.

The nerve is the largest in the human body unprotected by muscle or bone so injury is common this nerve is directly connected to the little finger and the adjacent half of the ring finger innervating the palmar aspect of these fingers. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The ulnar nerve runs from the neck to the shoulder down the back of the arm around the inside of the elbow and ends at the hand in the fourth and fifth fingers. Ac joint injuries are classified based on the severity of the injury to the ligaments and capsule surrounding the ac joint.
The ulnar nerve is a major peripheral nerve of the upper limb. An ac joint injury is measured in multiple grades grade 1 through grade 6.
