    Cranial nerves and Sacral spinal cord
  3. Sympathetic has long or short preganglionic nerves; long or short postganglionic nerves?
    Short preganglionic; long postganglionic
  4. Parasympathetic has long or short preganglionic nerves; long or short postganglionic nerves?
    Long preganglionic; short postganglionic
  5. Sympathetic releases _______ to _______ receptors preganglionic; releases _______ to _______ receptors postganglionic.
    • ACh to nAChR preganglionic
    • NE to adrenergic postganglionic
  6. Parasympathetic releases ______ to ______ receptors preganglionic; releases _____ to ______ receptors postganglionic.
    • ACh to nAChR preganglionic
    • ACh to mAChR postganglionic
  7. nAChR is ionotropic or metabotropic?
    Ionotropic
  8. 4 types of glial cells:
