  2. Median nerve - Wikipedia

    en.wikipedia.org/wiki/Median_nerve

    The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus. The median nerve originates from the lateral and medial cords of the brachial plexus, [1] and has contributions from ventral roots of C6-C7 (lateral cord) and C8 and T1 (medial cord). [1] [2]

  3. Thenar eminence - Wikipedia

    en.wikipedia.org/wiki/Thenar_eminence

    The muscles in this location are usually innervated by the recurrent branch of the median nerve. They all control movement of the thumb. The innervation of these muscles by the median nerve is unusual, as most of the intrinsic muscles on the palm of the hand are supplied by the ulnar nerve. The lateral two lumbrical muscles are the other exception.

  4. Proper palmar digital nerves of median nerve - Wikipedia

    en.wikipedia.org/wiki/Proper_palmar_digital...

    In the palm of the hand the median nerve is covered by the skin and the palmar aponeurosis, and rests on the tendons of the flexor muscles.Immediately after emerging from under the transverse carpal ligament the median nerve becomes enlarged and flattened and splits into a smaller, lateral, and a larger, medial portion.

  5. Median nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Median_nerve_palsy

    For patients with low median nerve palsy, it has been shown that the flexor digitorum superficialis of the long and ring fingers or the wrist extensors best approximate the force and motion that is required to restore full thumb opposition and strength. This type of transfer is the preferred method for median nerve palsy when both strength and ...

  6. Common palmar digital nerves of median nerve - Wikipedia

    en.wikipedia.org/wiki/Common_palmar_digital...

    In the palm of the hand, the median nerve is covered by the skin and the palmar aponeurosis, and rests on the tendons of the Flexor muscles.Immediately after emerging from under the transverse carpal ligament the median nerve becomes enlarged and flattened and splits into a smaller, lateral, and a larger, medial portion.

  7. Carpal tunnel - Wikipedia

    en.wikipedia.org/wiki/Carpal_tunnel

    In the human body, the carpal tunnel or carpal canal is a flattened body cavity on the flexor (palmar/volar) side of the wrist, bounded by the carpal bones and flexor retinaculum. It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand. [1]

  8. Anterior interosseous syndrome - Wikipedia

    en.wikipedia.org/wiki/Anterior_interosseous_syndrome

    The anterior interosseous nerve is a branch of the median nerve, with a large sensory branch to the wrist bones, which arises just below the elbow. It passes distally, anteriorly along the interosseous membrane and innervates flexor pollicis longus, flexor digitorum profundus to index and middle finger as well as pronator quadratus, and supplies sensory feedback from the wrist bones, i.e. the ...

  9. Palmar branch of the median nerve - Wikipedia

    en.wikipedia.org/wiki/Palmar_branch_of_the...

    Unlike most of the median nerve innervation of the hand, the palmar branch travels superficial to the Flexor retinaculum of the hand. Therefore, this portion of the median nerve usually remains functioning during carpal tunnel syndrome. [1]
