What is ulnar nerve?
Ulnar nerve is a nerve that runs along the length of the arm, starting with a brachial plexus and ending in pinky and annular finger. Nerves are structures similar to the cord in the body that give signals between the nervous system and other organs so that the body can feel and respond to stimuli such as pressure or temperature. They are divided into two groups according to the function: sensory or afferent group and engine or eperential group. The Ulnar nerve adds sensation and movement. Ulnar nerve then passes through the cubital tunnel in the elbow, joint of the joint between the upper arm and the forearm. Here the nerve gains its claim to fame as the cause of pain when a person hits a funny bone. For several centimeters around the elbow, Ulnar nerve is unprotected by bones or muscle, exposed to injuries that cause a strange, painful feeling when the elbow is hit.
The elbow passes Ulnar Nervis under Flexor Carpi Ulnaris, the forearm muscles and runs along the ulna, after which it is named. ATLNA is one of the two bones in the forearm that ends on the wrist on the side of the pinky. Ulnar nerve travels along the Ulnar artery and innervates the flexor Carpi Ulnaris and half the flexor digitorum pundus, another forearm muscle. Inevvate means adding nerves and thus feeling or movement, into the tissue. On the forearm Ulnar nerve branches into muscle branches, dorsal branches and a branch of Palmar to innervate different parts of the arm and hand.
The nerve then passes between the pisiform and the hamina of the wrist bones and in the palm of the hand through the Guyon Canal. Here, Ulnar nerve is divided into superficial and deep branches. The branches give a feeling and move on the palm of the palm side of the palm and the pinks of the finger and half the ring finger.
Ulnar capture is a relatively common condition in which the nerve is compressed or gripped. This usually occurs in the elbow, causing the tunnel cubic syndrome, but can also occur in the wrist, where it is called the Guyon stenosis of the channel. A patient with a tunnel cubital syndrome may result in a prolonged feeling of hitting a funny bone with symptomsInsensitivity and tingling in the pinky, annular finger and back of this half of the hand. The condition usually proceeds so that the symptoms last for a longer time. In the late stages, the patient may experience the ripple of the pinky and the ring finger called Ulnar Claw.
If the wrist compression occurs, the Ulnar claw may be more serious, but the back of the hand will retain a normal feeling. Cubital Tunnel Syndrome and Guyon Canal Stenosis can often be cured by changing positions for sleeping, avoiding the arm in one position for a long time and improving posture. If the basic cause consists of abnormality or disease in wrists, elbows, brachial plexus or spine, the condition may be treated with surgery. Ulnar nerve compression should not be confused with the carpal tunnel syndrome, which is the result of the middle nerve compression and causes dullness or armor in the thumb, index, in the middle and half of the annular finger.
