Which of the following insulates and protects a neuron's axon, as well as helps to speed along electrical impulses?
A) synaptic knobs
B) receptor sites
C) myelin sheath
D) neuromodulators

Question

Quizplus · Accepted Answer

The myelin sheath insulates and protects the axon of a neuron, and also helps to speed up electrical impulses by allowing them to jump from node to node along the myelin-covered sections of the axon. Synaptic knobs are structures at the end of axons that release neurotransmitters, receptor sites are specific locations on the dendrites of neurons where neurotransmitters bind, and neuromodulators are substances that regulate the activity of neurotransmitters. None of these are directly involved in insulating and speeding up electrical impulses along an axon.
