What is the cranial bone?

cranial bones are eight bones that make up the upper part of the skull that closes the brain. They consist of paired temporary and parietal bones and the only frontal, sphenoids, ethmoids and occipital bones. The clergy bones are connected to a special type of solid joint called seture. The bosses appear as jagged lines on the skull surface. Together, the skull bones form a skull, which is also called calvaria.

The front bones form the foreheads and peaks of the eye sockets. Each eye has a comb which forms the upper edge of the orbit. The frontal bone contains the frontal cavities and also forms a part of the structure that holds the frontal lobes of the brain. They create the main joints of the skull between themselves, the front bone and the occipital bone in the back of the skull. They are connected to the front bone at the coronal batch, which runs from the left of the skull. Parietal bones connect each other in the sagittal stitch on the ridge of the head that leads from the front to the back. In the back of the head they form a lambdoid stitch with an occipital bone and also with two squamous stitches where they encounter temporaryBones below them on both sides of the head.

Time bones are placed against each other under parietal bones. It lies under the temples and contains an outer ear canal where the sounds are transmitted to the inner ear. Time bones meet the facial bones on the ridge that leads from the face towards the ear. They also create two movable jaw joints where they meet the lower jaw.

Looking from the sides, the sphenoid bone seems to be two bones, but it is actually one bone that extends completely through the front of the skull. Sometimes described as bats, it has a few features called larger and smaller wings. Larger wings are located directly in front of time bones, while smaller wings are part of the eye orbit. The sphenoid bone forms a joint with each of the other skull bones, with the exception of the occipital bone.

Ethmoid bone is a thin bone located in the skull in front of and somewhat above the sphenoid bone. Form part of the nasal septum, jaLeat and part of the roof and sides of the nasal cavities. Ethmoid bone is the smallest and finest of the skull bones.
