What is the primary function of the myelin sheath in neurons? (2021)
To protect the neuron from damage
To increase the speed of nerve impulse transmission
To provide nutrients to the neuron
To facilitate synaptic transmission
The myelin sheath acts as an insulator and increases the speed of nerve impulse transmission through saltatory conduction.

Q: What is the primary function of the myelin sheath in neurons? (2021)
Solution: The myelin sheath acts as an insulator and increases the speed of nerve impulse transmission through saltatory conduction.
Steps: 5
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.
