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]
The recurrent branch of the median nerve is also colloquially called the "Million Dollar Nerve", because injury to this nerve during carpal tunnel surgery can lead to a million dollar lawsuit. Injury to this nerve can lead to loss of function of the thumb. Such injury can happen if the flexor retinaculum is transected too radially. The ...
Origin: Trapezium, flexor retinaculum: Insertion: Thumb, proximal phalanx: Artery: Superficial palmar arch: Nerve: Recurrent branch of the median nerve, deep branch of ulnar nerve (medial head) Actions: Flexes the thumb at the first metacarpophalangeal joint: Antagonist: Extensor pollicis longus and brevis: Identifiers; Latin: musculus flexor ...
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.
The medial root of median nerve is one of the two sources of the median nerve, the other being the lateral root of median nerve. [1] References This ...
The lateral root of median nerve is a source of the median nerve, originating off the lateral cord of the brachial plexus. [1] It is typically one of two nerve roots forming the median nerve, the other being the medial root, [1] although anatomical variations in which the median nerve instead has three or four nerve roots have been described in medical literature.
Origin: Medial epicondyle of the humerus (common flexor tendon) as well as parts of the radius and ulna: Insertion: Anterior margins on the base of the middle phalanges of the four fingers: Artery: Radial artery: Nerve: Median nerve: Actions: Flexor of fingers (primarily at proximal interphalangeal joints) Antagonist: Extensor digitorum muscle ...
Origin: The middle 1/2 of the anterior surface of the radius and adjacent to the interosseus membrane. Insertion: The base of the distal phalanx of the thumb: Artery: Anterior interosseous artery: Nerve: Anterior interosseous nerve (branch of median nerve) (C8, T1) Actions: Flexion of the thumb: Antagonist: Extensor pollicis longus muscle ...
