Which cell is a specialized nerve cell that transmits electrical impulses?

• A. Glial cell
• B. Neuron
• C. Erythrocyte
• D. Platelet

Answer: (B)

The cell that transmits electrical impulses is a neuron. Neurons are specialized to receive signals, process them, and send them along as electrical impulses called action potentials. They have dendrites to pick up information, a cell body for processing, and an axon to carry the signal long distances, often insulated by myelin to speed transmission. At the end of the axon, synapses release neurotransmitters to pass the signal to the next cell. Glial cells support neurons but don’t generate impulses themselves. Erythrocytes carry oxygen in the blood, and platelets help with blood clotting. So the neuron is the correct choice.
