Skull Cranial Bones

The skull is a bony case that protects the brain and the organs of special senses. It is further divided into the neurocranium and viscerocranium. The neurocranium or the braincase is composed of the cranial bones and its function is to house and protect the brain.

The viscerocranium is built by the facial bones and represents the skeleton of the face.

The cranial bones consist of two paired (temporal and parietal), and four single bones (frontal, occipital, sphenoid and ethmoid), joined together by immovable fibrous joints called sutures. 

In this chapter, we will help you learn the basic anatomy of the skull by simplifying the concepts as much as we possibly can.
