Question

Quizplus · Accepted Answer

An impulse does not cross the synapse by way of the myelin sheath. The myelin sheath is a fatty, insulating layer around the axons of some neurons that helps speed up the transmission of impulses. The actual crossing of the synapse involves the release of neurotransmitters from the synaptic vesicles of one neuron, which then bind to receptors on the dendrites or cell body of the next neuron, triggering the propagation of the impulse.
