    The outer membrane covering the brain and spinal cord
  17. Electroencephalography-(EEG)
    Recording of the electric currents generated by the brain; a tracing of brain waves.
  18. Electromyography-
    The insertion of needles into selected skeletal muscles for the purpose of recording nerve conduction time in relation to muscle contraction.
  19. Frontal-
    Anterior; the forehead bone; refers to the plane drawn through the side of the body from the head to the foot.
  20. Ganglion-
    A mass of nerve tissue that receives and sends out nerve impulses.
  21. Hypothalamus-
    A structure of the brain between the cerebrum and the midbrain; lies below the thalamus.
  22. Interneurons-
    Neurons connecting sensory to motor neurons.
  23. Longitudinal Fissure-
    The deep cleft between the two hemispheres of the cerebrum.
  24. Lumbar Puncture-
    The insertion of a needle between the vertebrae in the lumbar area for the purpose of withdrawing spinal fluid.

  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.
