Research Results For 'Lumbricals'

LUMBRICALS

The lumbricals (lumbricales manus) consist of four small, fleshy tissues that originate from the tendons of the deep flexor muscle, the flexor digitorum profundus and insert in the extensor tendon of each of the four fingers. The lumbricals are innervated by the radial and ulnar nerves and supplied by the palmar arch from the deep metacarpal artery. These muscles work to flex and extend the fingers. The first lumbrical moves the index finger, the second moves the middle finger, the third moves the middle and ring finger and the fourth moves the ring and little finger.

MUSCLES OF THE FEET

The feet and toes are essential elements in body movement. They bear and propel the weight of the body during walking and running, and help to maintain balance during changes of body position. The foot can adapt itself to different surfaces and absorb mechanical shocks as well. Each foot has about thirty-three muscles, some of which are attached to the lower leg. There are four plantar muscle layers. The first layer includes the adductor hallucis, the flexor digitorum brevis, and the abductor digiti minimi. The second layer consists of the lumbricals, and the third layer includes the flexor hallucis brevis, the adductor hallucis, and the flexor digiti minimi brevis. The fourth layer is composed of the interossei muscles.

PEDIS LUMBRICALS

The pedis lumbricals are four small lumbrical muscles that are associated with the tendons between the four small toes. The first muscle originates from the tendon of the flexor digitorum longus muscle on the tibial side of the second toe. The second, third, and fourth lumbricals originate from adjacent sides of the four tendons of the lexor digitorum longus muscle. They insert into the extensor tendons of the four toes. The lumbrical muscles are innervated by the lateral and medial plantar nerves and are supplied by the plantar artery. These muscles work with the tendons to flex the corresponding digital joint.
