Detailed explanation-1: -The nerve impulse travels in the form of electrical charge from axon end to the synapse. Here, the electrical impulse is converted to the chemical impulse in the synaptic cleft. Further this nerve impulse flows from synaptic cleft to dendritic tips, converting the chemical impulse to electrical impulse.

Detailed explanation-2: -This impulse travels from the dendrite to the cell body. From cell body, it passes on to the axon. It then travels along the axon to its tip. At the tip of the axon, the electrical impulse sets off the release of some chemicals (neurotransmitters).

Detailed explanation-3: -A motor neuron sends an impulse to a muscle or gland, and the muscle or gland then reacts in response. Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon.

Detailed explanation-4: -Impulse enters a neuron through the dendrites. The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that sends the impulse to the cell body where it is processed. From the cell body, the impulse moves into the axon and then to the axonal ends.
