• O nervo mediano é um dos nervos do membro superior mais acometidos pela hanseníase e o seu comprometimento pode resultar na perda da oposição do polegar. (bvsalud.org)
  • Na hanseníase um dos sinais de comprometimento motor do nervo ulnar é a atrofia de primeiro espaço interósseo. (bvsalud.org)
  • The voluntary responses of the facial muscles (eg, smiling when taking a photograph) arise from efferent discharge from the motor face area of the cerebral cortex. (medscape.com)
  • The facial motor nerves are represented on the homunculus diagram below with the forehead uppermost and the eyelids, midface, nose, and lips sequentially located more inferiorly. (medscape.com)
  • This homunculus illustrates the location on the motor strip of facial areas relative to the hand and upper extremities. (medscape.com)
  • Discharges from the facial motor area are carried through fascicles of the corticobulbar tract to the internal capsule, then through the upper midbrain to the lower brainstem, where they synapse in the pontine facial nerve nucleus. (medscape.com)
  • In 1987, Jenny and Saper performed an extensive study of the proximal facial nerve organizations in a primate model and found evidence that in monkeys, upper facial movement is relatively preserved in upper motor neuron injury, because these motor neurons receive relatively little direct cortical input.
