Bones of the skull
After completing this study unit you will be able to:
- Locate and identify the two main parts of the skull.
- Learn about the location and relations of the individual bones of the skull.
The human skull consists of 22 bones (or 29, including the inner ear bones and hyoid bone) that are mostly connected together by fibrous joints, so-called sutures.
The two main parts of the skull are the braincase (neurocranium) and the facial skeleton (viscerocranium). Its primary function is the protection of the brain. The mandible and the hyoid bone are technically not considered as part of the cranium and thus are sometimes referred to as extracranial bones.
This video tutorial will provide you with an overview of the bones of the skull.
