Answer:
Neurons communicate with each other by synapses
Step-by-step explanation:
Neurons send signals to other neurons through synapses. The most common type is chemical synapse; a chemical synapse occurs between the axon terminal of the neuron that sends the message and the dendrite of the neuron that receives the message. The first one is known as the presynaptic cell and the last one is known as the postsynaptic cell. Moreover, in a chemical synapse, the presynaptic and postsynaptic cells don’t touch each other as they are separated by a very tiny gap known as a synaptic cleft. The chemical synapse transforms an electrical signal (which is the action potential in the presynaptic cell’s axon) into a chemical signal (which is the neurotransmitter) and back to an electrical signal (the postsynaptic potential) in the postsynaptic cell.
