insulate axon to help send signal more quickly

Question 7

synapse

Answer 7

tiny gap between the ends of this cells axon and the dendrites of other neurons

Question 8

action potentials

Answer 8

electrical impulses that allows signals to travel from the dendrites to the axon

neuron communication…synapse

Answer 11

Question 12

reuptake

Answer 12

any remaining neurotransmitters in the synapse are taken back into the axon terminal
