15 Cards in this Set
- Front
- Back
|
Medulla
|
base of brain, controls heartbeat & breathing
|
|
|
Pons
|
base of brainstem, above medulla, coordinates movement
|
|
|
Reticular Formation
|
network of neurons inside the brainstem from spinal cord to thalamus, affects arousal, filters stimuli, relays info to other areas
(Damage here = coma) |
|
|
Thalamus
|
top of the brainstem, sensory switchboard (x smell)between cerebellum, medulla & cortex
|
|
|
Cerebellum
|
"little brain", rear of the brainstem, controls sensory input and output of voluntary movement, coordination & balance
(baseball movement) |
|
|
Limbic System
|
doughnut shaped system between brain stem and cerebral hemispheres, controls emotions, memory & drive, is made up of the amygdala, hippocampus, & hypothalamus
|
|
|
Amygdala
|
"almond shape", controls change in emotion up or down, placid or agressive, processing of emotional memories
|
|
|
Hippocampus
|
"sea horse", critical for memory (linked to ACh)controls memories linked to emotion & STM to LTM, next to the insula & the amygdala
|
|
|
Hypothalamus
|
"under" the thalamus(& over the pit. gland)controls hormones via the pituitary gland, ANS such as drink, food, temperature & linked to emotion & reward
|
|
|
Pituitary gland
|
part of the endocrine system, master control of hormones, yet controlled by the hypothalamus
|
|
|
Cingulate gyros
|
? located, involved w/attention
|
|
|
n.accumbens
|
? located, rich in DA (dopamine), related to schizo. and the reward system
|
|
|
Cerebral cortex
|
intricate fabric of interconnected neural cells that covers the cerebral hemispheres, it is the ultimate control & information processing center, 75+% are association areas
|
|
|
Motor cortex
|
at the back of the frontal lobe (precentral gyrus?), controls (output)voluntary movement, L side controls R movement & VV, more tissue for more important areas
|
|
|
Sensory cortex
|
just behind motor cortex & in front of parietal lobe (post central gyrus), recieves (input) of stimulus, R side rec. input for L side & VV, more tissue for more important areas
|
