Components

(generated)

Component items:

• Oculomotor Nucleus: Change Eye Direction
• Trochlear Nucleus: Control superior oblique muscles of eyes
• Edinger-Westphal Nucleus: Change Eye Pupil
• Mesencephalic Trigeminal Nucleus: unconscious proprioception from muscle spindles; facial somatic sensations from muscles of mastication, monosynaptic masticatory reflex
