What is the main function of cranium

Answer 1

HEY ANSWER IS.........#

The brain is  protected inside a bony box called cranium.The cranium is part of the skull that holds and protects the brain in a large cavity. Inside the box, the brain is contained in a fluid-filled balloon which provides further shock absorption. This fluid filled is cerebrospinal fluid. 

Fibrous joints or fixed joints are found in the flat skull bones which  fuse end-to-end with the help of dense fibrous connective tissues in the form of sutures, to form the cranium.
