The skull is the portion of the skeleton which supports the head and encases the brain inside the cranial cavity. The adult human skull consists of 22 bones.
We can divide the skull into two groups – the cranial bones (neurocranium) and the facial bones (viscerocranium). Most of these bones are attached to one another through immovable joints called sutures.
The cranial bones make up the braincase, which protects the brain, the meninges surrounding the organ, and the brain stem. It is composed of eight bones. The frontal and occipital bones, and the pair of parietal bones, form the cranial roof. Meanwhile, the cranial base is formed by six bones, including the sphenoid, ethmoid and frontal bones.
The facial bones provide structure to our faces. There are 14 viscerocranial bones in all. Some of these bones have added functions, such as assisting in breathing, and facilitating the act of chewing and eating. Examples of facial bones are the mandible and vomer, and the pairs of nasal, palatine, maxilla, zygomatic, and lacrimal bones.

More on the human Skull:
The human skull is composed of twenty-two bones. The cranial bones are the occipital bone, a frontal bone and a temporal bone. The facial skeleton consists of fourteen bones, including the sphenoid bone, the sphenoid bone, the parietal bone, and the ethmoid bone. The neurocranium, the central part of the skull, consists of the occipital bone, two temporal bones, and the sphenoid bone.
The human skull has three bones that form the base of the brain. These bones are called ethmoid and frontonasal bones. These two are connected by air clefts. The occipital bone forms the spine of the head. These three bones together form the base of the skull. The base of the skull is the most complex part of the skull, and the mandible and cranial bones are the most obvious parts of the face.
The human skull consists of 45 separate elements. It is relatively large, but it is not in proportion to the other parts of the body. It has a small facial area, which reflects the dominance of brain development. As a child grows older, the skull catches up with the development of the brain by developing the lower jaw and the upper jaw.
The skull also protects the inside of the brain, where the cerebrum, cerebellum and eye sockets are located. The facial bones make up the facial skeleton. The facial skeleton consists of a series of teeth and other bony structures that support the face.
The human skull is very complex. The cranium, the underlying part of the skull, is the part that protects the brain and sensory organs. The anterior cranial fossa is supported by the highest vertebra, the atlas. The atlas rotates on the next lower vertebra to allow for lateral movement.
The viscerocranium, or facial skeleton, is the upper part of the skull. The mandible is located at the base of the skull and forms the face. The face is the largest part of the skull. The face is composed of the frontal bone and the ethmoid bone.
The bones of the human skull must be studied carefully or you may forget the names of each bone. Check out the diagram on this website, which is interactive and online and contains all the bones that make up the heart.
