(121 cards)
parietal lobe
part of brain that processes bodily information
Neurons are composed of ____, ___, ___, ___, and ___ ___
nucleus, cell body, axon, dendrites and myelin sheath
Reversed prompt
type of monoamine in charge of motor behavior, motivation and emotional arousal; Parkinson’s disease, drug addiction, schizophrenia
dopamine
sympathetic nervous system
brainch of the ANS that produces rapid physical arousal in response to perceived emergencies or threats
What is a neuron’s resting potential?
-70 mV because of high [K+] inside neuron membrane
Reversed prompt
part of brain that connects spinal cord with rest of brain; sensory and motor pathways pass through here
hindbrain
autonomic nervous system
subdivision of the PNS that regulates involuntary functions
neuromodulators
diminish or increase effects of neurotransmitters
Reversed prompt
damage to Wernicke’s area and causes word salad
Wernicke’s aphasia
somatic nervous system
subdivision of the PNS that communicates sensory information to the CNS and carries motor messages fromt he CNS to the muscles
Reversed prompt
part of brain that is in charge of planning, initiating, and executing voluntary movements; impulse control
frontal lobe
Wernicke’s area
part of the brain in charge of word recognition
Reversed prompt
type of neuron that signals muscles to relax or contract
motor neurons
Glutamate
neurotransmitter that communicates excitation messages by creating active potential
hindbrain
part of brain that connects spinal cord with rest of brain; sensory and motor pathways pass through here
nodes of Ranvier
gaps between myelin sheaths
Broca’s aphasia
damage to Broca’s area and causes telegram; only nouns
Reversed prompt
type of monoamine in charge of sleep, wakefulness, and aggression; depression
seratonin
Reversed prompt
part of the brain that regulates glads and basic needs: feeding, fleeing, fighting, and fornication
hypothalamus
thalamus
part of the brain in charge of sensory relay; sends sensory information to the cortex
synaptic gap
tiny, fluid-filled space between presynaptic neuron and postsynaptic neuron
GABA (gamma-aminobutyric acid)
Neurotransmitter that communicates inhibitory messages; makes it more difficult to achieve action potential
dopamine
type of monoamine in charge of motor behavior, motivation and emotional arousal; Parkinson’s disease, drug addiction, schizophrenia
cortical localization
the notion that different functions are located or localized in different areas of the brain
