Question

In a neuron, conversion of electrical signal to a chemical signal occurs at

• A. Cell body
• B. Axonal end
• C. Dendritic end
• D. Axon

Answer 1

The correct option is B Axonal end

Signals are transferred from one neuron to another. The electrical signals are very fast as compared to that of chemical signals. Myelinated sheath present on the surface of neurons helps in better conduction of signals. At the end of the axon (axonal end), the electrical signal is converted into a chemical signal, and the axon releases chemical messengers called neurotransmitters (acetylcholine) which are received by their receptors on the dendrites of the subsequent neuron. This region is called synapse.

So, the correct answer is 'Axonal end'
