Which of the following is true about the functions of dendrites and axons?

• A. Dendrites receive signals from other neurons, while axons transmit signals away from the neuron.
• B. Both dendrites and axons transmit signals away from the neuron.
• C. Both dendrites and axons receive signals from other neurons.
• D. Axons receive signals from other neurons, while dendrites transmit signals away from the neuron.

Answer: (A)

Verified step by step guidance

1. Understand the basic structure of a neuron, which includes the cell body, dendrites, and axon.
2. Recognize that dendrites are branched extensions of the neuron that primarily function to receive signals from other neurons.
3. Identify that the axon is a long, singular extension of the neuron that transmits signals away from the neuron to other neurons, muscles, or glands.
4. Differentiate between the roles of dendrites and axons: dendrites receive incoming signals, while axons send outgoing signals.
5. Review the options provided and match them with the correct functions of dendrites and axons to determine the true statement.
