Unit 2 Flashcards
acetylcholine
affects muscle movement and memory (neurotransmitter)
dopamine
learning, attention, emotion (neurotransmitter)
serotonin
affects mood, hunger, and sleep (neurotransmitter)
norepinephrine
alertness and arousal (neurotransmitter)
GABA
inhibitory, calms you down (neurotransmitter)
glutamate
excitatory, involved in memory (neurotransmitter)
endorphins
neurotransmitters that relieve pain and elevate mood
hippocampus
(limbic system) processes short-term factual memory into long-term memory
amygdala
(Limbic system) involved in emotional like fear and anger
hypothalamus
(limbic system) animal-like instincts including hunger, thirst, sex drive, body temp
pituitary gland
(limbic system) master gland controls endocrine system, controlled by the hypothalamus
thalamus
sensory relay station
cerebellum
(brain stem) mini-brain, controls the memory of movement and balance, “auto-pilot”
cerebral cortex
the outer covering of brain includes all 4 lobes
frontal lobe
higher-level thinking and decision-making
motor cortex
outgoing messages of movement (frontal lobe)
Broca’s area
controls the movement of speech and formation of words (frontal lobe)
sensory cortex
incoming messages of touch (parietal lobe)
angular gyrus
reading (parietal lobe)
auditory cortex
hearing (temporal lobe)
Wernicke’s area
controls the understanding of speech/language (temporal lobe)
visual cortex
sight (occipital lobe)
pons
contains reticular formation (brain stem)
reticular formation
controls alertness, arousal, and sleep (brain stem)
medulla
controls vital functions (brain stem)
spinal cord
connects brain to nervous system
action potential
an electrical charge that travels down axon to axon terminals
