Dendrites primarily perform which function?

• A. Receive incoming signals from other neurons
• B. Transmit signals toward the cell body
• C. Integrate signals
• D. Release chemicals

Answer: (A)

Dendrites are the neuron's main input branches. They primarily receive signals from other neurons by binding neurotransmitters at synapses, converting those chemical messages into small electrical changes that travel toward the cell body. This reception provides the information the neuron can process and decide how to respond. The axon is the part that transmits signals away from the cell body, and neurotransmitter release happens at the axon terminals. While dendrites can contribute to local processing, their core role is to receive incoming signals.
