SKULL
The skull is formed by about 25 bones, the cerebral and facial sections are
distinguished. You can see front and side view of Human skull (figure 3)
Bones of the cerebral region: frontal, two parietal, two temporal, occipital,
wedge-shaped, latticed. All the bones of the cerebral part of the skull are
motionlessly connected to each other. In each temporal bone there is an opening of
the external auditory canal.
There is a large occipital opening in the lower surface of the occipital bone,
through which the skull cavity connects to the spinal canal. There are also small holes
in the bones of the base of the skull through which cranial nerves and blood vessels
pass into the brain.
Numerous bones of the facial region are also motionlessly connected to each
other, with the exception of the lower jaw, which in humans can move up and down
and right and left. The upper and lower jaws are the largest bones of the facial part
of the skull.
