- globus pallidus
the hypothalamus regulates - ANS eating/drinking
temperature
3 structures making up brainstem - ANS midbrain
pons
medulla
gray matter of spinal cord consists of - ANS -sensory neurons (dorsal)

which virus is known for laying dormant in the dorsal root ganglion until it becomes active and
travels down the sensory nerve fibers to the skin? - ANS varicella virus -> shingles
where in the spinal cord do you find alpha-motoneurons? - ANS ventral horn -> exits ventral
root
touch sensation varies in both __________ and ____________ - ANS amplitude and

Abeta fibers - ANS -fast
-myelinated
-discriminative touch
Adelta fibers - ANS -fast
-myelinated
-pain, temperature
C fibers - ANS -slow
-UNmyelinated, smaller diameter
-pain, temperature, itch, emotional touch
hair follicle receptors - ANS -spiral nerve endings around each hair bulb
-mechanoreceptors simulated by bending a hair
temporal summation - ANS ^ stimulus strength -> ^ receptor potential -> ^ frequency of
action potential -> ^ intensity of sensation
rapidly adapting receptors - ANS -AP only at onset & offset of stimulus
-sense rapidly changing stimuli
-phasic receptor
phasic receptor (rapidly adapting) - ANS a receptor in which the frequency of action
potentials drops rapidly as stimulation is maintained
slowly adapting receptors - ANS -respond throughout the stimulus duration
