Which part of the neuron receives messages from other neurons?

• A. Axon
• B. Dendrite
• C. Axon terminal
• D. Cell body (soma)

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the structure of a neuron. A neuron is composed of several parts: dendrites, cell body (soma), axon, and axon terminals. Each part has a specific function in transmitting and receiving signals.
2. Step 2: Learn the role of dendrites. Dendrites are branch-like structures that extend from the cell body. Their primary function is to receive signals (messages) from other neurons and transmit them to the cell body.
3. Step 3: Compare the functions of other neuron parts. The axon carries signals away from the cell body to other neurons, muscles, or glands. The axon terminal is the endpoint of the axon, where signals are transmitted to the next neuron or target cell. The cell body (soma) contains the nucleus and processes incoming signals.
4. Step 4: Identify the correct answer based on the function of each part. Since dendrites are responsible for receiving messages from other neurons, they are the correct answer.
5. Step 5: Reinforce the concept by visualizing the flow of information in a neuron: messages are received by dendrites, processed in the cell body, transmitted through the axon, and sent to the next neuron via the axon terminal.
