Know the names and functions of the 12 cranial nerves. I Olfactory smell – – II- sight – III- Oculomotor movement of eye – IV- Trochlear - movement of eye V Trigeminal nerve sensory for the face; chewing – VI Abducens nerve movement of eye – VII Facial taste; movement of face – VIII - Vestibulocochlear nerve and hearing –balance IX Glossopharyngeal nerve swallowing –taste; X Vagus nerves sensory and motor extending out of the head, helps control heart – rate and other functions in areas outside the head XI Accessory nerve movement of neck and upper back – XII Hypoglossal nerve movement of tongue – What are the 2 divisions of the autonomic nervous system? Know their functions, neurotransmitters, and effectors. Autonomic division of the PNS is divided into the sympathetic and parasympathetic divisions. Sympathetic functions in fight-or-flight response, is used during times of stress or unusual circumstances, functions include dilating pupils, inhibiting salivation and digestion, increases heart rate. Uses epinephrine and norepinephrine as its neurotransmitters. Effectors are glands, smooth muscle and cardiac muscle (all involuntary responses) Parasympathetic functions in the rest and digest mode of everyday, usual circumstances. Its functions include constricting the pupils, stimulating saliva flow and digestion, lowering heart rate. It uses acetylcholine (Ach) as its neurotransmitter and its effectors are glands, smooth muscle and cardiac muscle (also all involuntary responses).
