Answer 1

Here are the terms matched with the most accurate descriptions:

1) action potential - e) the reversal of the electrical potential in the plasma membrane of a neuron
2) afferent neuron - i) a type of neuron that sends information from the sensory receptors toward the central nervous system
3) dendrite - j) short, highly branched fibers that carry signals toward the cell body
4) interneuron - d) a type of neuron that sends information between sensory and motor neurons
5) axon - a) long fibers that carry signals away from the cell body
6) efferent neuron - h) a type of neuron that sends information away from the central nervous system to muscles or glands
7) neurotransmitter - f) a type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives
8) myelin sheath - g) the fatty material surrounding some axons
9) synaptic cleft - c) the space between two cells
10) Node of Ranvier - b) gaps in the myelin sheath
