Question

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

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

Answer 1

The correct option is B

axonal end

The correct option is B.

Explanation for correct option:

• The dendrites receive electrical impulses in the form of chemical signals through the synapse.
• These signals are converted to electrical signals in the dendrites.
• A nerve impulse is transferred through a neuron in the form of electrical signals from the dendrites to the axonal end or the axonal terminal of the neuron.
• The axonal end then converts these electrical signals into chemical signals that can be transferred to the next neuron.

Explanation for incorrect options:

Option A:

• The cell body of the neuron receives electrical signals from the dendrites and transfers them to the axon without converting them.

Option C:

• The dendritic end receives chemical signals through synapses and converts them into electrical signals.

Option D:

• The axon transfers electrical signals from the cell body to the axonal end without converting them.

Final answer: In a neuron, conversion of the electrical signal to a chemical signal occurs at/in the axonal end.
