Question

Electrical impulse travels in a neuron from:

• A. Nerve ending \( \rightarrow \) Axon \( \rightarrow \) Cell body \( \rightarrow \) Dendrite
• B. Dendrite \( \rightarrow \) Cell body \( \rightarrow \) Axon \( \rightarrow \) Nerve ending
• C. Cell body \( \rightarrow \) Dendrite \( \rightarrow \) Axon \( \rightarrow \) Nerve ending
• D. Dendrite \( \rightarrow \) Axon \( \rightarrow \) Nerve ending \( \rightarrow \) Cell body

Hint:

The electrical impulse travels through the neuron in a fixed direction: dendrite \( \rightarrow \) cell body \( \rightarrow \) axon \( \rightarrow \) nerve ending.

Answer 1

The Correct Option is B

A neuron's electrical signal follows this path:
- Dendrites: These neuron extensions get the signal.
- Cell body: The signal then goes to the cell body, housing the nucleus.- Axon: Next, the signal moves down the axon, a long, thin fiber.- Nerve endings: Finally, the signal reaches nerve endings (axon terminals) to transmit to the next neuron or muscle.Therefore, the correct sequence is (B) Dendrite \( \rightarrow \) Cell body \( \rightarrow \) Axon \( \rightarrow \) Nerve ending.
