Lumbricals Of The Hand: Origin, Insertion, Action, Innervation

Di: Stella

Structure The lumbricals are four, small, worm-like muscles on each hand. These muscles are unusual in that they do not attach to bone. Instead, they attach proximally to the tendons of the palm that of Extrinsic/intrinsic muscles (flexor, extensor) in hands & fingers: how many are there, list of names with anatomy, innervation, action, mnemonics, & labeled diagram

The lumbrical muscles of hand are four slender, worm-like (resembling lumbricus) intrinsic muscles located deep within the midpalmar space. They are unique among hand muscles as Clinical Significance Claw hand deformity: Paralysis of the lumbricals leads to hyperextension at MCP joints and flexion at IP joints (especially in ulnar nerve injury affecting medial lumbricals). Origin: Tendons of flexor digitorum profundus Insertion: Extensor expansions of digits 2-5 Action: Flexion of metacarpophalangeal joints. Extension of interphalangeal joint
