Overview Functions

protecting and supporting the organs of brain and other sense organs ； dealing with sight, hearing, balance and upper parts of digestive system & respiratory system.

we will spend 1 week, two times to finish this content we don’t study the separated bones respectively. We will study the skull as a whole
