ANS (Autonomic Nervous System)s a component of the peripheral nervous system that regulates involuntary process including:
- Heart Rate
- Blood Pressure
- Respiration
- Digestion
- Sexual Arousal

Cranial Nerves with Parasympathetic System:
- III (Oculomotor Nerve)
- VII (Facial Nerve)
- IX (Glossopharygeal)
- X (Vagus)
Movement of the eye muscles, constriction of the pupil, focusing with the eyes & the position of the upper eyelid.
III (Oculomotor Nerve)
Works with other cranial nerves to control eye movements and support sensory functioning.
III (Oculomotor Nerve)
carries nerve fibers that control facial movement and expression.
VII (Facial Nerve)
carries nerves that are involved in taste to the anterior 2/3 of the tongue and producing tears (lacrimal gland)
VII (Facial Nerve)
It is one of the four cranial nerves that has sensory, motor, and parasympathetic functions.
IX (Glossopharygeal)
