Ulnar Nerve

The Ulnar Nerve is one of the main nerves of the brachial plexus. It originates from the C8-T1 spinal nerves and runs down the medial aspect of the shoulder in the medial groove of the biceps brachii muscle.

Next, the ulnar nerve descends along the medial side of the elbow in the ulnar groove on the forearm, where, together with the artery of the same name, it passes to the palm through the ulnar canal.

The ulnar nerve innervates the muscles of the forearm and hand responsible for fine motor skills and grasping movements - flexor carpi ulnaris, flexor digitorum ulnaris, hypothenar muscles and interosseous muscles of the hand.

The nerve also provides sensitive innervation to the skin of the ulnar side of the palm and the back of the hand, V, IV and partially III fingers. It innervates the elbow and wrist joints, as well as the joints of the hand.

Damage to the ulnar nerve due to injury or disease leads to disruption of the motor and sensory functions of the corresponding parts of the upper limb.

The ulnar nerve is one of the main nerves in the brachial plexus. It passes down the medial groove of the biceps brachii and along the ulnar groove of the forearm, where it, together with the artery of the same name, crosses the palm. This nerve innervates the skin on the back of the hand, on the fifth, fourth and part of the third fingers, as well as on the elbows, wrist joints and joints of the hand, as well as the muscles of the forearm and hand.

Nerves are blood vessels that carry essential nutrients and oxygen to the cells and tissues of our body. These special structures, consisting of neurons, are necessary to ensure the normal functioning of all organs of our body. There are many different types of nerves in our body, each with a specific function. One such nerve is the Ulnar nerve, which belongs to the brachial plexus. Our article will tell you more about it.

The elbow nerve is one of the most important nerves in the shoulder region. It runs down the inside of the arm to the elbow, then along the radial groove of the palm to the ring and little fingers. The primary function of the elbow nerve is to control flexion and extension of the arm, as well as movement of the wrist and finger. In addition, the elbow nerve is also responsible for innervation of the skin in the area of ​​the wrist ligament, dorsum of the hand, metacarpus, ring and little fingers, elbow, as well as some muscles of the shoulder, forearm and fingers.

To function properly, the elbow nerves must be protected to prevent damage and dysfunction. However, when our arms are frequently bent and extended at the elbows, the nerve endings can be subject to pressure and kinking. This may cause numbness, tingling and other types of pain.
