Document Summary

The skull encloses and protect our brain (which is the most important organ) Provides bony framework for soft tissues of the head & neck (e. g. to make our jaw chew) Hold different viscera / other structures (e. g. eyeball, inner ear, our mouth) There are 2 sub regions in the skull: Neurocranium more delicate, forming the vault around the brain: composed of 8 bones, divided in 2 parts: calvaria & base. Viscerocranium host the organs of the face (i. e. nose, eyes, mouth : facial skeleton, makes up the face, composed of 14 bones. If we break the viscerocranium into 7 pieces we will study all these 14 individual bones throughout the different lectures. In this lecture, we will mostly talk about the neurocranium. The primary role of the neurocranium is to protect the skull: frontal, parietal (x2, temporal (x2, occipital, sphenoid, ethmoid, frontal forms the forehead.
