Anterior interosseous nerve syndrome: Damage to the anterior interosseous nerve (a motor branch of the median nerve) causes weakness or paralysis in the thumb and index finger.You may experience finger pain, wrist pain and numbness.

What conditions and disorders affect the median nerve? This system sends signals from your brain to the upper limbs, lower limbs and certain organs.įour other nerves also aid arm movements and sensations: The nerves in the arm are part of your peripheral nervous system. Palmar branch: Sends sensory information to and from the palm, thumb and some of the fingers.Deep (volar interosseous) branch: Controls deeper muscles in the front part of the forearm.Muscular branch: Controls movement in the forearm’s superficial muscles, close to the skin.Enters the hand through the carpal tunnel, a space in the wrist that holds the median nerve and tendons.Travels with the ulnar nerve down the forearm, where it branches into smaller nerves.Crosses in front of the brachial artery and goes under the bicipital aponeurosis, a broad band of connective tissue in the cubital fossa (triangular space opposite the elbow joint).Runs along the inside of the upper arm between the bicep and triceps tendons, next to the brachial artery.Connects to nerve roots in the brachial plexus that run from the C5 to C8 cervical vertebrae and the T1 thoracic vertebra.The median nerve starts at the armpit and: You have a left and right median nerve - one for each side of the body.
