Verified step by step guidance
1
Step 1: Understand the structure of a neuron. A neuron is composed of several key parts: dendrites, cell body (soma), axon, and axon terminal. Each part has a specific function in transmitting and processing signals.
Step 2: Focus on the function of dendrites. Dendrites are branch-like extensions of the neuron that are specialized to receive incoming signals (electrical or chemical) from other neurons or sensory receptors.
Step 3: Compare the function of dendrites with other parts of the neuron. The cell body (soma) processes the signals received by the dendrites, the axon transmits signals away from the cell body, and the axon terminal releases neurotransmitters to communicate with other neurons.
Step 4: Recognize that the dendrites are the primary structures responsible for receiving incoming signals, as they are designed to increase the surface area for communication with other neurons.
Step 5: Conclude that the correct answer is 'Dendrites,' based on their specialized role in signal reception, distinguishing them from the other parts of the neuron.
