Answer;
-Axon; dendrites
When a neural signal is transmitted, it leaves the axon of the first neuron and is received by the dendrites of the second neuron.
Step-by-step explanation;
-Electrical events propagate a signal within a neuron, and chemical processes transmit the signal from one neuron to another. The chemical process of interaction between neurons occur at the end of the axon, in a structure called synapse.
-When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite.
