Which term describes the neurocranium (calvaria), the skull portion that contains the brain and its meninges?

Explanation:
The skull is organized into two main parts: the neurocranium and the viscerocranium. The neurocranium forms the protective case around the brain, including the skull cap (calvaria) and the cranial base, and houses the brain and its protective meninges. That makes it the term that best describes the portion containing the brain and its meninges. In contrast, the viscerocranium is the facial skeleton, comprising bones of the face. Canaliculi and osteon are microscopic bone features—tiny channels and the basic unit of compact bone, respectively—not terms for skull regions.
