The upper part of the skull that covers the brain, excluding the face and jaw.
The surgeon carefully examined the calvarium during the operation.
Calvarium is derived from the Latin "calvaria" (meaning skull or the upper part of the skull). The suffix "-ium" is often used in Latin to denote a place or a structure. Thus, calvarium refers to the structure or place of the skull.
Think of 'calvaria' as the Latin word for skull, and remember that 'calvarium' refers to the structure of the skull.
