Answer:
A nerve impulse from one neuron affects the activity of a neighboring neuron at a point of interaction called the: SYNAPSE
Explanation:
A NEURON(or nerve cell) has 3 parts:
1. The dendrites(multiple)
2. The axon
3. The cell body
A SYNAPSE is an area where the dendrites of one neuron communicates with the axon of another neuron.
At the synapse, nerve impulses are transmitted from one neuron to the other. This is possible through substances called NEUROTRANSMITTERS. There is no direct contact between the axon of one neuron and dendrites of another neuron.
