  30. Motor-
    Refers to the nerves that permit the body to respond to stimuli.
  31. Myelography-
    an X-ray examination of the spinal cord following an injection of a radiopaque material.

    Pertaining to the sense of smell.
  34. Optic-
    Pertaining to the eye or sight.

    Innermost of the three meninges of the brain and spinal cord.
  39. Plexuses-
    A network of nerves.
  40. Pons-
    A portion of the brainstem connecting the medulla oblongata and cerebellum with upper portions of the brain.
  41. Positron Emission Tomography-(PET scan)
    A form of imaging permitting visualizing the physiologic function of the body.
  42. Sciatica-
    Inflammation and pain along the sciatic nerve felt at the back of the thigh running down the inside of the leg.
  43. Sensory-
    Refers to the nerves that receive and transmit stimuli from the sense organs.
  44. Skull X-ray-
    A radiologic examination of the skull.
