Document Summary
The bones of the skull are part of the axial skeleton. The skull is composed of 22 bones. 8 form the cranium or braincase > surround and protect the brain. 14 are associated with the face > protect and support such things like eyes and the entry point for the respiratory tract. Sutures are considered fibrous joints based on structure and immoveable - synarthrotic joints based on function. There are an additional 7 bones associated with the skull [i. e. the 6 auditory ossicles (ear bones) (3 within each temporal bone) and the 1 hyoid bone]. These bones surround and protect the brain. These bones also provide attachments sites for head and neck muscles. The cranium can be divided into the calvaria (the bald part of the skull) and the cranial base. The four bones marked with the * create the calvaria, also known as the cranial vault or. Skullcap , which forms the superior, lateral, and posterior aspects of skull.
