An electrical nerve impulse is carried by:
A)the cytoplasm of the neuron
B)the membrane of the neuron
C)the myelin sheath around the neuron
D)the neurolemma around the neuron

Question

Quizplus · Accepted Answer

The electrical nerve impulse is carried by the membrane of the neuron, specifically in the form of an action potential which travels down the axon. The cytoplasm of the neuron and the myelin sheath can facilitate this process, but they do not carry the impulse itself. The neurolemma is also involved in the transmission of nerve impulses, but is not directly responsible for carrying the electrical signal.
