Lumbrical Muscles And Bursae Spaces And Sheaths Schema The lumbrical muscles of the hand are numbered 1 4 from the most radial lateral to the most ulnar medial. each lumbrical muscle originates from one or two adjacent tendons of the flexor digitorum profundus muscle. lumbricals 1 2 are usually unipennate, meaning their fibers arise obliquely from one tendon, while lumbricals 3 4 are bipennate. Gross anatomy. the four lumbricals arise from the tendons of the flexor digitorum profundus (fdp). the first and second lumbricals arise from the radial side of the fdp tendons of the index and middle fingers. the third lumbrical arises from the adjacent tendons of the middle and ring finger while the fourth arises from the adjacent tendons of. The muscles of the left hand. palmar surface. (first lumbricalis labeled at bottom right of muscular group) the lumbricals are deep muscles of the hand that flex the metacarpophalangeal joints and extend the interphalangeal joints. it has four, small, worm like muscles on each hand. these muscles are unusual in that they do not attach to bone. Lumbricals (4 muscles) origin. fdp tendon. insertion. radial lateral band of the extensor expansion (tendon) action. extends pip and dip joint. innervation. 1st & 2nd lumbricals: median nerve.

Second, third, & 4th lumbrical sheaths are not so easily demonstrated, but when present usually overlie mid palmar bursa or space; lumbar sheaths extend from the web area to the center of the palm; pus from a web area can ascend index lumbrical sheath and rupture into thenar bursae or space;. The hand is distal to the forearm, and its skeletal framework includes the carpus, or wrist. in lay usage, however, the word "wrist" is used for the distal end of the forearm, a wrist watch being worn over the lower ends of the radius and ulna. the position of the hand at rest is shown in figure 11 1. the hand is of enormous importance.
