What are the nerves of the arm?

The nerve system innervates - or adds the organs or muscles nerves - parts of the upper arm, forearm and hand. There are four main nerves of the arm and bother around the bones. Ulnar and middle nerves come from a brachial plexus, a bundle of nerve fibers ranging from spinal cord to arm and ends in hand. The radial nerves cover the brachial plexus and forearm. Muscutaneous nerves stem from the brachial plexus, through biceps and forearms. Despite the passage of the upper arms, Ulnar nerves do not provide the nerves of this area. However, the forearm and hand have the nerves of Ulnar. In addition, Ulnar nerve provides a sense of touch of the ring and a small finger in what is called skin innervation. The injury of Ulnar nerves of the arm brings a loss of adhesion and can also defend someone to fill someone with your fingers. The result is a disease known as claws where someone's hand or fingers appear curved.

Medium nerves are also the nerves of the arm that go throughThe arm and hand. Like Ulnar's nerves, the middle nerves do not throw the upper arm, but add the muscles to the forearm and their hand nerves. Medium nerves end up in the thumb, index and middle fingers and provide these fingers. The most likely consequences of injury to this nerve are a limited range of motion in the thumb or impaired mobility in the index and middle fingers.

Radial nerves are the nerves of the arm that give the upper arm nerves. Like the above nerves, the radial nerves in the brachial plexus begin and continue in their positions in the arm - in this case the triceps muscle. Radial nerves also innervate the muscles in the forearm. Although these nerves at the end of the forearm, radial nerves also provide skin innervation in the back of the hand. Damage to radial nerves can lead to loss of muscle in triceps and cause loss of adhesion.

Muscutaneous nerves are paid primarily at the top of the arm. These arm nerves are associated with biceps muscle and provide a feeling of this area. Out of four primariesThe shoulder nerves are musclocutaneous nerves most susceptible to injury due to their connection to frequently used biceps muscles.
