Question

In a nerve cell (neuron), the conversion of electrical signal to chemical signal occurs in/at:

• A. dendritic end
• B. cell body
• C. axon
• D. axonal end

Answer 1

The Correct Option is D

The conversion of an electrical signal (nerve impulse) to a chemical signal occurs at the axonal end (or synaptic terminal) of a neuron. Here, the electrical impulse triggers the release of neurotransmitters, which are chemical messengers that transmit the signal across the synapse to the next neuron. The dendrites receive signals, the cell body integrates signals, and the axon transmits signals.
