Research Results For 'Ulnar Nerves'

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.

SPINAL NERVES

The spinal nerves are those which originate in the spinal cord and carry impulses to muscles (and other structures) and from sensory organs. They feature both efferent and afferent nerves. Efferent nerves send impulses out to the muscles and other structures and connect with the spinal cord in the anterior roots. Afferent nerves carry impulses from sensory organs to the spinal cord and connect in posterior roots. The spinal nerves include, in alphabetical order, the celiac, the femoral, the genitofemoral, the gluteal, the hemmorhoidal, the hepatic, the hypogastric, the iliohypogastric, the ilioinguinal, the intercostal, the intercostobrachial, the interosseus, the median, the mesenteric, the musculocutaneous, the obturator, the pelvic, the peroneal, the phrenic, the pudendal, the radial, the renal, the saphenous, the scapular, the thoracic, the tibial, and the ulnar nerves.

ULNAR NERVES

The ulnar nerves branch off of the spinal cord between the eighth cervical and first thoracic vertebrae. They extend down the arm and innervate the ulnar side of the forearm, wrist, hand, and fingers.
