Components
(generated)
Component items:
- Oculomotor Nucleus (LPC.MM.OCN): Change Eye Direction
- Trochlear Nucleus (LPC.MM.TRH): Control superior oblique muscles of eyes
- Edinger-Westphal Nucleus (LAC.MM.EWN): Change Eye Pupil
- Mesencephalic Trigeminal Nucleus (LPC.MM.MSTR): unconscious proprioception from muscle spindles; facial somatic sensations from muscles of mastication, monosynaptic masticatory reflex
