What are the relevant parts of your skull as a whole
prisoha [69]

Answer:

The human skull consists of 22 bones (or 29, including the inner ear bones and hyoid bone) which are mostly connected together by ossified joints, so called sutures. The skull is divided into the braincase (neurocranium) and the facial skeleton (viscerocranium). Its main task is the protection of the most important organ in the human body: the brain.

The brain is almost entirely enclosed by the neurocranium with the exception of the foramen magnum and other foramina at the skull base which serve as entry and exit point for blood vessels and cranial nerves. Also, the skull provides support for all of the facial structures.
