The primary purpose of the myelin sheath is to a. insulate the neuron so it can transmit information more efficiently b. receive messages from outside the neuron and carry them to the cell nucleus c. provide a place for neural respiration and cell metabolism to occur d. provide a soft covering to hold axons in place

The myelin sheath is an extended and modified plasma membrane that is spirally wrapped around the axon of the neuron. The primary purpose of the myelin sheath is to a. insulate the neuron so it can transmit information more efficiently and quickly. A myelinated neuron can transmit the electrical impulses at the speed of 400 Km/h whereas the speed is just 4 Km/h in a non-myelinated or a damaged neuron.

it takes hundreds of years to become stable.

if you have another question lmk.
