Bones of the head and neck: skull and cervical spine (preview) - Human Anatomy | Kenhub

The head is comprised of many bones that form a shell-like bony structure that protects the brain - the skull. While the bony framework of the neck is defined by the cervical vertebrae. Check out the full video here: https://khub.me/859xd

The skull is made up of over twenty individual bones that as we know can be divided into two groups – those of the neurocranium and those of the viscerocranium. The neurocranial portion of the skull houses and protects the brain, whereas the viscerocranial portion forms the face.

The first bone that we'll look at in the full version of this video is the frontal bone. This unpaired bone which is one of the bones that encases the brain consists of three parts – the squamous part which makes up the largest portion of the frontal bone encompasses the area of the forehead and houses the frontal sinuses, the orbital part which is essentially the part of the frontal bone that contributes to the bony orbit or eye socket and finally, we have the nasal part which articulates with the frontal processes of the maxilla and the nasal bones.

If we view our skull from the side, we can see the temporal bone. This paired bone forms part of the base of the cranial vault and is made up of four parts – the squamous part, the tympanic part, the styloid process, and the petromastoid part which includes the mastoid process of the skull. Along with forming part of the base of the cranial vault, the temporal bones also participate in the formation of the lateral walls of the skull.
