Which part of the neuron typically receives incoming signals from other neurons?
Correct answer: B. Dendrites
- A. Axon
- B. Dendrites
- C. Myelin sheath
- D. Synaptic knob
Explanation
Dendrites are the short branched processes that carry receptors for neurotransmitter and conduct the resulting signal towards the cell body. The axon carries impulses away, and its synaptic knobs are where transmitter is released rather than received. Myelin is an insulating sheath that speeds conduction and plays no part in reception.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
