NEET BIOLOGY

Detailed explanation-1: -The electrical impulse is converted into the chemical impulse in the synaptic cleft. Therefore, conversion of an electrical signal into a chemical signal occurs at the axonal end.

Detailed explanation-2: -To cross the synaptic cleft, the cell’s electrical message must be converted into a chemical one. This conversion takes place when an action potential arrives at the axon tip, resulting in depolarization.

Detailed explanation-3: -The dendritic end receives chemical signals through synapses and converts them into electrical signals.

Detailed explanation-4: -So, the correct answer is ‘Axonal end’

Detailed explanation-5: -An action potential, also called a nerve impulse, is an electrical charge that travels along the membrane of a neuron. It can be generated when a neuron’s membrane potential is changed by chemical signals from a nearby cell.
