What is Nerve Damage to the Arm & Hand? The Median Nerve travels down the front of your arm and enters into the palm of your hand. The classic Median Nerve injury is carpal tunnel syndrome (see talk here), where pressure slowly develops within the carpal tunnel and pinches this nerve causing numbness in the hand and weakness in the thumb.

Peripheral Nervous System: Spinal Nerves and Plexuses Nerve Plexuses. A nerve plexus is a network of nerves that seem to be tangled that mostly serve the limbs. Each network is a network of nerves that come together and then redistribute themselves out with a different distribution of nerves into the limbs.ive nerves innervate the muscles of the arm: 1  Musculocutaneous innervates the biceps brachii and some overlying skin. ( 2 C5, C6, C7). 3  Median innervates anterior forearm muscles, some intrinsic hand muscles, and skin of lateral (anatomical position/toward thumb) palm.

- Pinched median nerve A pinched median nerve in your wrist can lead to pain, numbness and weakness in your hand and fingers (carpal tunnel syndrome). A pinched nerve occurs when too much pressure (compression) is applied to a nerve by surrounding tissues. In some cases, this tissue might be bone or cartilage, such as in the case of a herniated spinal disk that compresses a nerve root. In other cases, muscle or tendons may cause the condition.

Ulnar nerve In human anatomy, the ulnar nerve is a nerve that runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest unprotected nerve in the human body, so injury is common. This nerve is directly connected to the little finger, and the adjacent half of the ring finger, innervating the palmar aspect of these fingers, including both front and back of the tips, perhaps as far back as the fingernail beds. This nerve can cause an elec

Causes of a Numb Thumb or Hand The superficial branch of the radial nerve is responsible for delivering sensation from the back of the hand, thumb, and first two fingers to the brain. If the radial nerve is interrupted, numbness of the back of the hand can result. Damage to the radial nerve is less common than the medial nerve. The trauma is also more obvious, as well. Rather than a subtle swelling pinching the nerve, the cause may be a bone fracture in the hand, for example.

Shoulder Injuries and Disorders Because the carpal tunnel is somewhat narrow, a major nerve called the median nerve that passes through this tight space can become irritated or compressed. Carpal tunnel syndrome is a combination of numbness, tingling, pain and weakness in the hand caused by compression of the median nerve in the carpal tunnel. Symptoms tend to show up most in the thumb, index finger, middle finger and half of the ring finger because the median nerve provides sensation to those areas.

- Ulnar nerve decompression. The ulnar nerve is a nerve which supplies sensation and strength to a portion of the hand and forearm. It may become compressed or trapped as it courses past the olbow. Ulnar nerve decompression at the elbow is performed when the ulnar nerve is entrapped at the elbow. The pressure on the ulnar nerve may cause pain or numbness and tingling in the little finger and half of the ring finger. There may be weakness as well.

A to Z List of Neurological Disorders Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist. The carpal tunnel—a narrow, rigid passageway of ligament and bones at the base of the hand—houses the median nerve and the tendons that bend the fingers.

CARPAL TUNNEL SYNDROME Carpal tunnel syndrome is a common condition caused by compression of the median nerve as it passes through a tunnel into the hand. This is usually felt as pain, tingling or numbness in part of the hand, usually the thumb, index and middle fingers. Sometimes the symptoms are felt in the whole hand.

What is the Median Nerve? The median nerve is the nerve that runs through the carpal tunnel of the wrist and connects with the thumb and all fingers of the hand, with the exception of the little finger. This nerve originates with the cervical spine and is routed through the arm and forearm. The nerve gathers in compressed form to run through the narrow carpal tunnel and to the fingers. In addition to controlling sensation in the hand, it is also important to the general nerve function of the upper portion of the arm. In relation to the hand, the median nerve controls all sensation and nerve function on the palm side of the thumb. The nerve also manages the process of sensation for the index and middle fingers, and half of the ring finger.

Carpal Tunnel Syndrome The median nerve provides feeling and movement to the thumb side of the hand, including the palm, thumb, index finger, middle finger, and thumb side of the ring finger. The area in your wrist where the nerve enters the hand is called the carpal tunnel. This tunnel is normally narrow. Any swelling can pinch the nerve and cause pain, numbness, tingling or weakness. This is called carpal tunnel syndrome. Some people who develop this problem were born with a carpal tunnel that is small. Carpal tunnel syndrome may be caused by making the same hand and wrist motion over and over.

What is carpal tunnel syndrome? Carpal tunnel syndrome is the compression of the median nerve as it passes into the hand. The median nerve is located on the palm side of your hand (also called the carpal tunnel). The median nerve provides sensation (ability to feel) to your thumb, index finger, long finger, and part of the ring finger. It supplies the impulse to the muscle going to the thumb.
