Location of ulnar nerve

Answer 1

The ulnar nerve is a large branch of the medial cord. It splits from the medial cord in the shoulder, and descends along the medial aspect of the arm, passes under the medial epicondyleof the humerus and then along the forearm between flexor carpi ulnaris and flexor digitorum profundus. It then enters the hand, where it supplies most of its muscles and skin with innervation. It is also responsible for the sensation when you "hit your funny bone"; the nerve is squashed on the medial epicondyle.

Answer 2

The main function of the ulnar nerve is to spread the fingers apart and close them while keeping them straight. It enables you to squeeze objects while keeping your fingers straight. In other words,it's your key pinch. It gives the fingers and thumb the dexterity to manipulate objects. The ulnar nerve literally sucks the fingers and thumb to close the hand while keeping the fingers straight. It would be difficult to play a musical instrument,deal a pack of playing cards,etc. or anything that requires fine finger movement. The ulnar nerve is what most people call the funny bone and it actually controls all the small muscles in the hand. If this nerve is injured, you will lose feeling and function in the pinky,half of the ring finger and the thick part close to the pinky finger. Although you won't lose feeling in the rest of the fingers,thumb and hand,you will lose 80% of the function.

Answer 3

I had that done with an elbow replacement, what they doo it they carefully move it out of the way of the joint, because it runs virtually between the bones at the joint in its natural position. The result is that you end up with tingling in the fingers for up to several months until it settles down. It took mine about 4 months.

Answer 4

It's located in the wrist. Hold your hand out with the palm upward. Follow your middle finger towards your elbow - to a point about two-fingers width past the base of your thumb. You should feel your ulnar pulse there.
