Quizplus · Accepted Answer

A chemical synapse is the junction between two neurons where neurotransmitters are released from the presynaptic neuron to the postsynaptic neuron. Schwann cells are responsible for producing myelin sheaths around axons in the peripheral nervous system, unsheathed nodes refer to nodes of Ranvier without a myelin sheath, and sodium gates are channels that allow for the movement of sodium ions across the neuronal membrane. Therefore, the correct answer is B, which is the only choice that specifically refers to the junction between two neurons.
