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

The electrical impulse in a neuron travels in a specific sequence:
- The impulse is received by the dendrites, which are extensions of the neuron that receive signals.
- It then travels to the cell body, where the nucleus is located. - From the cell body, the impulse travels down the axon, which is a long, thin structure that conducts the electrical signal.
- Finally, the impulse reaches the nerve endings (axon terminals) where it is transmitted to the next neuron or muscle. Thus, the correct answer is (B) Dendrite \( \rightarrow \) Cell body \( \rightarrow \) Axon \( \rightarrow \) Nerve ending.
