  1. sensory for smell
    Olfactory
  2. sensory for vision
    optic
  3. sensory for proprioception from muscles served
    Oculomotor
  4. motor to 4 of 6 extrinsic eye muscles which are responsible for movement of the eyeball:
    superior rectus
    Medial rectus
    inferior rectus
    inferior oblique
    Oculomotor
  5. motor to "levator palpebrae superioris" which opens the upper eyelid
    Oculomotor
  6. motor to intrinsic eye muscle "ciliary muscle" which changes shape of lens for near or far vision- accommodation
    oculomotor
  7. motor to sphincter muscle of iris which changes size of pupil controlling amount of light (only constriction)
    Oculomotor
  8. sensory for proprioception of muscle innervated
    • Trochlear
    • Trigeminal
    • Abducens
    • Facial
    • Glossopharyngeal
    • Accessory
    • Hypoglossal
  9. motor to the "superior oblique" extrinsic muscle of the eye involved in movement of eyeball
    trochlear
  10. motor to muscles of mastifcation- control chewing
    Trigeminal
  11. sensory from face,mouth, and teeth for touch, pain, and temperature
    Trigeminal
  12. motor to the "lateral rectus" extrinsic muscle of the eye involved in movement of eyeball
    Abducens
  13. Motor to facial, scalp, and neck muscles involved in facial expressions
    Facial
  14. motor to lacrimal and salivary glands- stimulaes secretion of saliva and tears
    Facial
  15. sensory for taste from the anterior 2/3rds of tongue
    facial
  16. sensory for hearing and equilibrium
    Vesibulocochlear
  17. sensory for taste from posterior 1/3rd of tongue
    Glossopharyngeal
  18. sensory from carotid sinus for regulation of blood pressure
    Glossopharyngeal
  19. motor to swallowing muscles of pharynx
    Glossopharyngeal
  20. motor to parotid gland- stimulates salivation
    Glossopharyngeal
  21. sensory and motor innervating most viscera, pharyngeal and laryngeal muscles for swallowing, laryngeal muscles for speech, heart and lungs, smooth muscle of digestive tract, taste buds of throat
    vagus
  22. motor for muscles involved in swallowing
    accessory
  23. motor to trapezius and sternoclleidomastoid- therefore coordinates head movements
    accessory
  24. motor to tongue muscles- involved in tongue movements for speech and swallowing
    hypoglossal
