Question

multiple choice question
what is the function of the myelin sheath?
increase the speed of neurotransmitter diffusion across the synaptic cleft
inhibit impulse transmission
increase the speed of impulse transmission

Explanation:

The myelin sheath is a fatty - insulating layer around nerve fibers. It allows for saltatory conduction, which greatly increases the speed of nerve impulse transmission. It does not affect neurotransmitter diffusion across the synaptic cleft and does not inhibit impulse transmission.

Answer:

Increase the speed of impulse transmission
