where does your ulnar nerve start
Ulnar nerve. The ulnar nerve is a nerve that travels from the wrist to the shoulder. This nerve is mainly responsible for movement of the hand; despite passing through the forearm, it is only responsible for one and a half muscles there.Its primary role is to provide nerve function to the hand.his means that general damage to the arm or elbow can cause damage to the ulnar nerve. The ulnar nerve is responsible for the pain, or 'funny bone', sensation that occurs if the elbow bone is suddenly struck. Continual pressure on the elbow or inner forearm may cause damage.
