Some of the sutures in the skull take a few months-to-years after birth to completely form. The brain is encased in the cranium of the skull. The bones that make up the cranium are called the cranial bones. The remainder of the bones in the skull are the facial bones.
The skull is made up of 22 different bones – 8 cranial bones that enclose your brain within the neurocranium, and 14 facial skeleton bones. There are also 6 ear bones. With the exception of the mandible, the bones of the skull are joined by sutures, which are a kind of joint that is synarthrodial – in other words, it can’t move.
Skull, skeletal framework of the head of vertebrates, composed of bones or cartilage, which form a unit that protects the brain and some sense organs. The upper jaw, but not the lower, is part of the skull.
