MICROANATOMY

Detailed explanation-1: -Final answer: The electrical impulse travels in a neuron from Dendrite → cell body → axon → axonal end.

Detailed explanation-2: -Answer and Explanation: An action potential (nerve impulse) is an electrical signal that travels down the axon of a neuron, resulting in the release of neurotransmitters into the synapse.

Detailed explanation-3: -Action potential – Brief ( 1 ms) electrical event typically generated in the axon that signals the neuron as ‘active’. An action potential travels the length of the axon and causes release of neurotransmitter into the synapse.

Detailed explanation-4: -Two mechanisms have evolved to transmit nerve signals. First, within cells, electrical signals are conveyed along the cell membrane. Second, for communication between cells, the electrical signals generally are converted into chemical signals conveyed by small messenger molecules called neurotransmitters.

Detailed explanation-5: -When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite.
