One of the five main nerves originating from the brachial plexus. It is the only nerve passing through the carpal tunnel, where it may be compressed to cause carpal tunnel syndrome.
A nerve that arises by two roots from the medial and lateral cords of the brachial plexus. The controls sensation of the central palm, the thumb, and the first three fingers, as well as the ability to oppose the thumb to the fifth finger.
A combined motor and sensory nerve of the arm having its origin in the brachial plexus.
Sensory-motor nerve, smaller than the ulnar and radial nerves that, with its branches, supplies the arm and hand.
An intricately woven neural pathway traversing from the wrist and extending into the hand, granting sensory perception and contributing to the mobility of the hand, including the thumb, index finger, middle finger, and a portion of the ring finger.
A prominent nerve within the arm, the median nerve emanates from the brachial plexus and traverses from the shoulder down to the hand. It governs the muscles responsible for flexing the wrist, fingers, and thumb, as well as those that rotate the forearm to face inward. Additionally, the nerve transmits sensations from the thumb and the initial three fingers, including the base of the palm in that area.
Injury to the nerve can arise due to harm to the shoulder, a Colles’ fracture located slightly above the wrist, or compression of the nerve as it travels through the wrist (known as carpal tunnel syndrome). Indications of nerve impairment encompass numbness and diminished strength in regions regulated by the affected nerve.
