Median nerve
The median nerve is a Nerf Upper limb at the man.
Anatomy
The median nerve is born from the meeting of the secondary trunks antéro-médial and antéro-side of the Plexus brachial in the area axillaire. The rachidian roots on which depends the median nerve are C5, C6, C7, C8 and T1.The median nerve goes down in the former cabin from the arm then from the Avant-bras until the Carpel tunnel finishing in the hand.
Branches and innervation
- higher nerve of the round Muscle pronator
- lower nerve of the round pronator
- nerve of the flexor long Muscle of the inch
- nerve of the deep Flexor of the fingers
- nerve of the surface Flexor of the fingers
- nerve of the long Muscle palmar
- nerve of the radial Flexor of the carpus
- nerve of the square Muscle pronator
- palmar cutaneous nerve
- nerve of the short delivery Muscle of the inch
- nerve of the adverse Muscle of the inch
- nerve of the short flexor Muscle of the inch
- nerve of the two first lombricaux
Pathology
- Syndrome of the peripheral carpel tunnel
- Neuropathy of the median
- Traumatism and wound of the median
Flexor carpi ulnaris gold the medial two digits off Flexor digitorum profundus , which are supplied by the Ulnar nerve.
Median The beg the Muscle S in the Thenar eminence off the Hand by has off recurring thenar branch, and the side two Lumbrical muscle S. The rest the intrinsic muscles off the hand are supplied by the ulnar nerve.
In terms off sensory information, the median nerve cutaneously innervates the palmar side off the Thumb, the index and Middle finger, and half the Boxing ring finger. It also receives information from the Nail bed off thesis Finger S. The proximal share off the palm is supplied by has off palmar branch, the palmar cutaneous brach the median nerve which leaves the nerve proximal to the Wrist creases. This palmar cutaneous branch travels in has separate fascial groove adjacent to the flexor carpi radialis.
Median The nerve is the only nerve that master keys through the Carpal tunnel, so it plays has big part in Carpal tunnel syndrome. -->
