Document Summary
Good way to remember: an old olympus" towrering top, a finn and german view some hops" autonomic nervous system connections: Two divisions: sympathetic, arouses the body for action, flight / fight response, parasympathetic, calms body down. Spinal cord connected to a chain of autonomic control centers: in sns: connects with sympathetic ganglia, in pns: connects with parasympathetic ganglia. Sacral region: part of pns that connects directly to the spinal cord. Brainstem begins where spinal cord enters the skull and extends upward into lower area of forebrain. Distinctive feature: has many cranial nerve nuclei that converge at its core. Its structures integrate voluntary and involuntary body movement and contribute to sleep- wake cycle. Reticular formation: a network": controls sleep and wake (maintains arousal / consciousness, damage: permanent unconsciousness. Nuclei in pons (upper brainstem): take inpute from cerebellum to rest of brain. Nuclei in lower brainstem (medulla: regulate vital functions such as breathing.
