Vedclass · Answer

(A) The myelin sheath is a lipid-rich layer that surrounds the axons of many neurons. It acts as an electrical insulator. By insulating the axon,the myelin sheath prevents the nerve impulse (action potential) from leaking out to adjacent nerve fibers,thereby ensuring that the signal is transmitted efficiently and rapidly along the axon. Thus,both the statement and the reason are correct,and the reason provides the correct explanation for the function of the lipid-rich myelin sheath.

$S$ - Statement: The myelin sheath around a nerve fiber contains lipids.
$R$ - Reason: This sheath prevents the impulse from leaking into adjacent nerve fibers.
