A nerve which runs from the neck to the elbow and controls the muscles in the forearm and some of the fingers.
Nerve, a branch of the brachial plexus, that supplies the skin and muscles of the little-finger side of the forearm and hand; it is the funny bone of the elbow.
One of the major nerves of the arm. It originates in the neck, from spinal roots of the last cervical and first thoracic divisions, and runs down the inner side of the upper arm to behind the elbow. In the forearm it supplies the muscles with motor nerves; lower down it divides into several branches that supply the skin of the palm and fourth and fifth fingers.
A major nerve in the arm, it runs from the brachial plexus to the hand. The nerve controls the muscles that move the fingers and thumb and conveys sensation from the fifth and part of the fourth and from the adjacent palm. Muscle weakness and numbness in the areas supplied by the nerve is usually caused by pressure from an abnormal outgrowth from the epicondyle at the bottom of the humerus.
Sensory-motor nerve that, with its branches, affects the little-finger side of the arm and palm of the hand.
The ulnar nerve, which courses in proximity to the ulna bone, provides innervation to the little finger and ring finger. Notably, it is the longest exposed nerve in the human body, often associated with an aching or tingling sensation when one accidentally strikes their “funny bone.”
One of the major nerves in the arm is the ulnar nerve. Originating from the brachial plexus, the ulnar nerve travels down the entire arm and extends into the hand. Responsible for governing the muscles that control thumb and finger movements, the ulnar nerve also carries sensory information from the fifth finger, a portion of the fourth finger, and the region of the palm adjoining these fingers.
Impact to the olecranon process, the rounded projection at the elbow’s tip through which the ulnar nerve travels, can lead to a sensation of pins-and-needles and pain in the forearm, along with the fourth and fifth fingers. Similarly, repeated pressure on the elbow, such as leaning on it, can produce a comparable effect.
Continued loss of sensation and diminished strength in regions governed by the ulnar nerve might stem from an unusual bony growth originating from the upper-arm bone, known as the humerus. This growth could be linked to osteoarthritis or a fracture of the humerus. Surgical intervention becomes necessary to alleviate the nerve’s compression. If left unaddressed, this condition could lead to lasting harm to the ulnar nerve, potentially resulting in a condition known as claw-hand.
