Which part of the neuron receives impulses from other neurons?

• A. Axon
• B. Dendrites
• C. Myelin sheath
• D. Synapse

Answer: (B)

Dendrites are the parts of a neuron that receive impulses from other neurons. They branch out to contact many neurons and have receptors for neurotransmitters released into the synapse. When a neurotransmitter binds to these receptors, the signal is conducted toward the cell body and then along the neuron. The axon, by contrast, carries impulses away from the cell body toward other cells; the myelin sheath speeds up this transmission but does not serve as the receiving site; and the synapse is the contact point where communication occurs, not the receiving structure itself.
