Flashcards covering key concepts related to the nervous system and cranial nerves.

Autonomic Nervous System

The part of the nervous system that controls involuntary bodily functions, such as digestion and heart rate.

Sympathetic Nervous System

The division of the autonomic nervous system responsible for the body's 'fight or flight' response.

Parasympathetic Nervous System

Oculomotor Nerve

Cranial nerve number three, controlling four of the six extrinsic eye muscles.

Cranial nerve number five, responsible for sensation in the face and motor functions such as biting and chewing.

Vagus Nerve

Cranial nerve number ten, involved in autonomic control of the heart, lungs, and digestive tract.
