Questions & Step-by-Step Solutions
What is the primary function of the myelin sheath in neurons? (2021)
Step 1: Understand that neurons are cells that send signals in the body.
Step 2: Learn that the myelin sheath is a protective layer that surrounds some neurons.
Step 3: Know that the myelin sheath acts like insulation, similar to how plastic covers electrical wires.
Step 4: Realize that this insulation helps signals travel faster along the neuron.
Step 5: Understand that the speed increase happens through a process called saltatory conduction, where signals jump from one gap in the myelin to another.
