Nerve impulses are electrical signals produced by which of the following?
A)nodes of Ranvier
B)lipid sheath of Schwann cell

D)synapse
E)neuromuscular junction

Question

Quizplus · Accepted Answer

Nerve impulses are electrical signals that travel down the plasma membrane of the neuron, specifically the axon, which is responsible for transmitting signals to other neurons or effectors (such as muscles or glands). The node of Ranvier and lipid sheath of Schwann cells are important for the proper propagation and insulation of the nerve impulse, but the electrical signal itself is generated by the plasma membrane. The synapse and neuromuscular junction are sites where the nerve impulse is transmitted to other cells or tissues, but they do not generate the impulse themselves.
