Which is the correct pathway for information flow through a neuron?

• A. Axon → Cell body → Dendrite
• B. Dendrite → Cell body → Axon
• C. Axon → Dendrite → Cell body
• D. Cell body → Axon → Dendrite

Answer: (B)

Verified step by step guidance

1. Understand the structure of a neuron: Neurons have three main parts - dendrites, cell body (soma), and axon.
2. Dendrites receive signals from other neurons or sensory cells. They are the input region of the neuron.
3. The cell body processes the information received by the dendrites. It contains the nucleus and is responsible for maintaining the cell's health.
4. The axon transmits the processed information away from the cell body to other neurons, muscles, or glands. It is the output region of the neuron.
5. Therefore, the correct pathway for information flow through a neuron is: Dendrite → Cell body → Axon.
