The Neuron - AP Psychology, Neuron Labeling AP Psychology Flashcards

14918524993	Dendrites	Part of neuron that receives messages from other neurons	0
14918524994	Axon	wire-like structure that extends from cell body & connects terminal bulbs	1
14918524995	Axon Terminal (Bulbs)	End of neuron, where message exits and enters synapse	2
14918524996	Myelin Sheath	a fatty covering around axon of some neurons that speeds neural impulse	3
14918524997	Cell body	Contains nucleus and DNA of neuron	4
14918524998	Nucleus	Center of cell body (Soma), contains DNA	5
14918524999	Synapse	Space between two neurons where chemical messengers cross - junction where end of axon meets another cell's dendrite	6
14918525000	receptor sites	holes in surface of dendrites shaped to fit specific neurotransmitters	7
14918525003	mirror neurons	Frontal lobe neurons that fire when performing certain actions or when observing another doing so. - brain's mirroring of another's action may enable imitation, language learning, and empathy	8
14918525004	Interneurons	neurons that internally communicate and intervene between sensory inputs/motor outputs	9
14918525006	dendrites	receive messages from other cells	10
14918525007	axon	extension of a neuron through which messages pass to other neurons, muscles, or glands	11
14918525008	terminal branches of axon	form junctions with other cells	12
14918525009	myelin sheath		13
14918525005	how does a neural impulse travel?	travels down the axon	14
14918525010	cell body	Largest part of neuron; contains the nucleus and much of cytoplasm	15
14918636089	action potential	neurons fire electrical impulses generated by stimuli	16
14918641909	threshold	level of stimulation required to trigger a neural impulse	17
14918669986	axon from one cell connects to dendrites of ______ cells	other	18
14918673959	excitatory signals	get neurons going	19
14918678877	inhibitory signals	slow neurons down	20
14918684887	sensory neuron	send info from organs/tissues to brain	21
14918690495	interneurons	allow for understanding messages from sensory neurons	22
14918695693	motor neurons	brain sends signals to body in response to signals received	23
14918722879	reuptake	leftover chemicals in synapse gap reabsorbed by sending neuron	24
14918740037	neurotransmitters fit in receptor like a	lock and key	25
14918745683	dopamine	movement, learning, attention, emotion	26
14918749390	serotonin	mood, hunger, sleep, arousal (antidepressants raise levels)	27
14918759231	norepinephrine	alertness	28
14918762129	acetylcholine	learning, memory, muscle contractions	29
14918765231	endorphins	chemicals released during pain/vigorous exercise	30
14918771491	drugs	substance that copies/blocks neurotransmitters	31
