Morphology
unmyelinated = myelinated (transparent) = un + myelin + ate + ed
Formed by adding the negative prefix 'un-' to 'myelinated'; the meaning is directly 'not covered with myelin'.
Etymology
Unmyelinated breaks into un- 'not' and myelin, a word from Greek meaning 'marrow' that is related to the English word 'marrow'. Myelin is a fatty 'sleeve' or covering around many nerve fibers, so unmyelinated means 'not having this covering', which is why these fibers carry signals more slowly.
