Which term refers to the group of bones forming the head?

• A. Joint
• B. Cranium
• C. Cranial bones
• D. Skull

Answer: (B)

The main idea here is naming the bones that surround and protect the brain. The cranium refers specifically to the bones that form the braincase—the head’s protective bony enclosure. It’s made up of eight bones (such as the frontal, parietal, temporal, occipital, sphenoid, and ethmoid) and excludes the facial bones and the jaw. That focus on the braincase makes cranium the best term for the group of bones forming the head in this context. In contrast, a joint is a connection between bones, not a group of bones itself, and cranial bones refer to the individual bones that compose the cranium rather than the whole braincase as a unit. The skull is a broader term that can include the facial bones, which is why it’s not as precise for this wording.
