What does calvaria mean?
The calvaria is the upper, dome-shaped portion of the skull — sometimes called the skullcap — that forms a protective vault over the brain. Anatomically, it comprises the frontal, parietal, and occipital bones (along with parts of the temporal and sphenoid bones) united by fibrous sutures, and it excludes the facial skeleton and the base of the skull. The word belongs to the technical vocabulary of anatomy, neurosurgery, physical anthropology, and forensic science, where precision matters: a report may describe a fracture of the calvaria or note the thickness of calvarial bone in a graft. Its plural is calvariae. Though obscure to lay readers, the term carries an intriguing linguistic history: it derives from the Latin calvaria, meaning 'skull' but literally 'that which is bald', the same root behind the name Calvary, the hill of the Crucifixion. Knowing the calvaria gives you exact anatomical language for the part of the body everyone can picture but few can name.
nounThe upper domelike portion of the skull, forming a vault that encloses and protects the brain; in anatomy, the skullcap proper, excluding the facial bones and the base of the skull.
- The upper domelike part of the skull that encloses the brain; the skullcap.
"The neurosurgeon carefully removed a section of the calvaria to access the underlying tissue."
"Anatomists describe the calvaria as consisting of the frontal, parietal, and occipital bones joined at the sutures."
"The forensic team examined the calvaria for evidence of blunt-force trauma."
The Latin-style plural calvariae is standard in anatomical and medical literature when referring to multiple specimens or individuals.
"The museum's comparative collection displays calvariae from several hominin species."
The dome of your skull has its own formal name — and it shares a root with the hill called Calvary, since both trace back to the Latin for 'bald'.

Etymology of calvaria
The word comes from Latin calvaria, literally 'a bare skull' and figuratively 'a bald head', derived from calva ('the scalp') and ultimately from calvus ('bald'). Medieval anatomical Latin adopted the term to designate the top of the skull. It entered English scientific usage in the early modern period as anatomy developed its Latinate vocabulary. The place-name Calvary (Golgotha, 'place of the skull') derives from the same Hebrew-Latin tradition, making the two words etymological cousins rather than one being named after the other.
How calvaria is actually used
A technical term used almost exclusively in anatomy, medicine, anthropology, and forensic science; rarely encountered in everyday speech. In strict anatomical usage it names the skullcap without the facial skeleton or cranial base. The adjective form "calvarial" appears frequently in medical literature.
Easily confused with calvaria
"Calvary" is the hill near Jerusalem where Christ was crucified (and the root word here), while "calvaria" is an anatomical term for the dome of the skull.
"Cranium" refers to the entire skull or braincase including its base and jaw-related structures, whereas "calvaria" denotes only the upper vault-like cap of the skull.
