  4. What divides the alar and basal plates?
    Sulcus limitans
  5. What lies between plate lies between the dorsal median sulcus and sulcus limitans?
    Basal plate (alar is more lateral)
  6. How many inches long is the spinal cord?
  7. Between what levels is the the cervical and lumbar enlargments?
    • Cervical C5-T2

    dorsal medial thalamic nuclei
  21. what do cranial nerves III, IV, and VI all pass through?

    trochlear nerve
  25. where is the nucleus of the abducens nerve found?
    pontine part of the floor of the 4th ventricle
  26. Where does the abducens nerve exit the brain stem?
    middle of the ponto-medullary junction
  27. what nerve(s) may be damaged if a patient presents with diplopia?
    CN III, IV, VI

    foramen rotundum
  30. What foramen does the mandibular division exit the skull through?
    foramen ovale

    (Mandible looks like a valley)
  31. where does the ophthalmic division of the trigeminal nerve exit the skull?
    superior orbital fissure
  32. what division of the trigeminal nerve carries efferent motor?
  33. What glands does the facial nerve transmit parasympathetic fibers too?
    • Submandibular
    • Sublingual
