Question 1

neuron

Answer 1

a nerve cell that receives and transmits neural information

Question 2

sensory neuron (afferent)

Answer 2

carry information towards CNS

Question 3

motor neurons (efferent)

Answer 3

the response message travels through the motor neurons to muscles or gland

Question 4

interneurons

Answer 4

rely messages between sensory and motor neurons, found in CNS

Question 5

dendrite

Answer 5

receive messages from other cells or receptors

Question 6

cell body

Answer 6

converts the neurotransmitter chemical messages to electrical messages to an electrical message

Question 7

axon

Answer 7

carriers action potential

Question 8

axon terminal

Answer 8

receives electrical messages and releases stored neurotransmitter chemical

Question 9

neuromodulator

Answer 9

a chemical molecule that has an effect on multiple postsynaptic neurons

Question 10

neurotransmitter

Answer 10

a chemical molecule that has an effect on one or two postsynaptic neuron

Question 11

excitatory neurotransmitter

Answer 11

increases the chance of an action potential forming in post synaptic neuron

Question 12

inhibitory neurotransmitter

Answer 12

decreases the chance of an action potential forming in post synaptic neuron

Question 13

glutamate neurotransmitter

Answer 13

primary excitatory neurotransmitter
enhances neural transmission by making the post synaptic neuron more likely to fire

Question 14

GABA neurotransmitter

Answer 14

primary inhibitory neurotransmitter
makes post synaptic neurons less likely to fire an action potential

Question 15

dopamine neuromodulator

Answer 15

responsible for regulating voluntary movement, the experience of pleasure and reward base learning

Question 16

serotonin neuromodulator

Answer 16

regulating mood and sleep and generally has an inhibitor effect on post synaptic neuron
