Lab 22: Brain Flashcards
(24 cards)
gyrus
where neurons communicate
precentral gyrus
primary motor cortex; initiate conscious motor control
post central gyrus
primary sensory cortex; integrate sensory information from the body
frontal lobe
voluntary movement, decision making, problem solving, personality, speech
brocas area
speech
wernickes area
language comprehension
parietal lobe
sensory perception and integration
temporal lobe
hearing, language comprehension, memory
occipital lobe
vision/visual processing
insula lobe
processing visceral, auditory and gustatory sensations
corpus callosum
enables communications from both sides
thalamus
relay center for sensory/motor infromation
hypothalamus
maintains homeostasis
mamillary bodies
function in recollective memory
infundibulum
allows hypothalamus to control hormone release from pituitary
pituitary gland
master gland
mid brain
relaying conscious motor control from cerebrum
mid brain plays a key role in
vision, hearing , sleep/wake regulation, arousal, temp control
cerebral peduncles
nerve fibers carrying motor signals
superior colliculi
involved in visual reflexes
inferior colliculi
involved in auditory reflexes
pons
relay center for sensory information; involuntary action (swallowing)
cerebellum
coordinate and smooth ongoing body movement; balance
medulla oblongata
autonomic control and relay center for sensory info
