ANATOMY

Detailed explanation-1: –When the nerve impulse passes through the first axon and reaches the dendrites at the end of the axon, chemical messengers called neurotransmitters are released.-Neurotransmitters travel through the synapse between the axon and the dendrite of the next neuron and bind to the dendrite membrane.

Detailed explanation-2: -Within a neuron, the impulse moves to the tip of an axon and causes the release of neurotransmitters, chemicals that act as messengers. Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell.

Detailed explanation-3: -The transmission of nerve impulses through chemical synapses is mediated by neurotransmitters. There is a fluid-filled space between the two neurons called the synaptic cleft. The nerve impulse cannot jump from one neuron to another. Axon terminals have a knob-like structure, which contain synaptic vesicles.
