Explanation:
Detailed explanation-1: -Dendrites are the first part of a neuron which receives an electrical impulse. The axon carries the message from the cell body or cyton of one neuron to the other or to the target cell.
Detailed explanation-2: -Signals are received through the dendrites, travel to the cell body, and continue down the axon until they reach the synapse (the communication point between two neurons).
Detailed explanation-3: -The cell that sends the nerve impulse is called the presynaptic cell, and the cell that receives the nerve impulse is called the postsynaptic cell. Some synapses are purely electrical and make direct electrical connections between neurons.
