A myelin sheath is like:

Question

Quizplus · Accepted Answer

A myelin sheath is a layer of insulation that covers nerve fibers and allows messages to travel more efficiently through the nervous system. This is similar to the insulation on a wire, which allows electrical signals to travel more efficiently through the wire. The other choices (tuning dial, layers of a cake, thermostat) don't have the same function or purpose as a myelin sheath.
