what is the cns made of
brain and spinal cord
what is the cns made of
cranial and spinal nerves that branch out from brain and spinal cord to muscles and organs
what are the functions of the pns
sensory, motor
two parts of autonomic motor function in pns
sympathetic and parasympathetic
autonomic nervous system (parasympathetic/sympathetic function)
controls internal milieu like peristalsis of stomach, heart rate, blood pressure, pupil dilation, salivation, etc)
difference of sympathetic or parasympathetic
sympathetic (fight or flight, purpose is selective energy expenditure for intense activity)
parasympathetic (rest and digest, purpose is to reduce energy expense and build reserves)
location of ganglia in cns and pns
cns (close to target organ)
pns (far from target organ)
what is a ganglion
cluster of cell bodies
why is white matter white
myelinated axons
what are the parts of the brain stem
medulla, pons
midbrain function
auditory and visual center like eye movement
cerebellum
muscle and reflex coordination, balance, fine motor movements
parts of diencephalon
thalamus and hypothalamus
thalamus function
sensory and motor relay
