Question: What is the primary function of the myelin sheath in neurons? (2021)

Options:

Correct Answer: To increase the speed of nerve impulse transmission

Exam Year: 2021

Solution:

The myelin sheath acts as an insulator and increases the speed of nerve impulse transmission through saltatory conduction.

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.
