. Axons with such a covering are called as myelinated or medullated and those without are called as non-myelinated or non-medullated. The function of myelin sheath is to increase the speed of conduction of the impulse. There is another cellular covering surrounding the axon, called neuril..

The aldehydes and ketones have carbonyl group as the functional group. The carbonyl carbon sp 2 hybridized and thus has three sp 2 hybrid orbitals and one unhybridized p-orbital. It uses sp 2 hybrid orbitals to form three s -bonds one with oxygen atom and remaining two with two other atom..
