In fishes, no distinct cranial vault as such exists. Instead, the skull is composed of loosely jointed bones. The cranial vault as a distinct unit arose with the fusion of the skull roof and the endocranium on the early Labyrinthodonts. [2] In amphibians and reptiles, the vault is rather small and inconspicuous, only forming proper vaults in ...
The base of skull, also known as the cranial base or the cranial floor, is the most inferior area of the skull. It is composed of the endocranium and the lower parts of the calvaria . Structure
In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [1] [2] is the upper and back part of the skull, which forms a protective case around the brain. [3] In the human skull, the neurocranium includes the calvaria or skullcap. The remainder of the skull is the facial skeleton.
Skull in situ Human head skull from side Anatomy of a flat bone – the periosteum of the neurocranium is known as the pericranium Human skull from the front Side bones of skull. The human skull is the bone structure that forms the head in the human skeleton. It supports the structures of the face and forms a cavity for the brain. Like the ...
Dr. Profitt in his Contemporary Orthodontics textbook [8] gave a good example of impact of brain growth on the cranial vault. He states that when the soft tissue of brain grows, the cranial vault follows the growth. Another example is hydrocephaly where increased intracranial pressure leads to increased size of the cranial vault. He also ...
The calvaria is the top part of the skull. It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. [1]

The cranial cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain. The remainder of the skull is the facial skeleton. The meninges are three protective membranes that surround the brain to minimize damage to the brain in the case of head trauma ...
