as a conduit that carries motor information from the brain to the body
and sensory information from the body to the brain. It is a critical

(dilation of pupils)
Parasympathetic nervous system
✓ autonomic activity, but it represents the opposite end of the spectrum
from sympathetic nervous system activity. It is sometimes called the
rest-and-digest system, as it is the activity that dominates when you are
not threatened and are less alert and anxious. It is the type of activity
that dominates after you've just eaten a large meal and are relaxing
on the couch. It causes digestion to increase, respiration to slow down,
heartrate to slow down, etc. so your body can restore itself.
central nervous system
✓ brain and spinal cord
peripheral nervous system
✓ nerves to and from CNS
