Check out our tutorial on the lumbricals of the hand a group of intrinsic muscles which flex the metacarpophalangeal joints and extend the interphalangeal.

The lumbricals assist in metacarpophalangeal joint flexion. The intrinsic muscles include the following musclesgroups. The lumbrical muscles of the hand are intrinsic muscles of the hand associated with the flexor digitorum profundus FDP tendon.

The structure indicated is the first lumbrical muscle of the hand. The 2 medial lumbricals are bipennate and are innervated by the deep branch of the ulnar nerve. Denervation of these muscles is the basis for the ulnar claw and hand of benediction.

These are four lumbricals in the hand each associated with a finger. They are small slender muscles one for each digit. The functions of the lumbricals are flexion of the proximal.

Lumbricals of hand Origin. The lumbricals arise from the sides of the tendons of the flexor digitorum profundus. This mnemonic recalls the four intrinsic muscles of the hand innervated by the median nerve whereas all the other intrinsic muscles are ulnar nerve.

Lumbrical muscle tightness caused by adaptive shortening is not to be confused with Lumbrical-Plus Finger1 where the FDP is lacerated or too long distal to the lumbrical origin and the onlyfirst available connection to finger movement is via the intact lumbrical. The lumbricals belong to the intrinsic group of muscles which act on the hand. The lumbricals of hand consist of four intrinsic muscles of the fingers that originate from the tendon of the digitorum profundus.

They are named lumbricals because of their elongated worm-like shape L. From adjacent sides of medial three tendons of the flexor digitorum profundus. Anatomically they are highly specialized in terms of their architectural properties with a.
