(a) What is myelin?

(b) How does the myelination process differ in the CNS and PNS?

(a) Contrast unipolar, bipolar, and multipolar neurons structurally.

(b) Indicate where each is most likely to be found.

What is the polarized membrane state? How is it maintained? (Note the relative roles of both passive and active mechanisms.)
