The outer layer of tissue that covers the surface of the skull.
The surgeon carefully examined the pericranium before proceeding with the operation.
Pericranium → It is formed from "peri-" (meaning around) and "cranium" (from Greek "kranion", meaning skull). The word refers to the tissue surrounding the skull.
Think of something that is 'around' ('peri-') the 'skull' ('cranium') — that's why pericranium means the tissue surrounding the skull.
