Question: 1 / 400

Which bone forms the forehead and contains the frontal sinuses?

Zygomatic bone

Nasal bone

Frontal bone

The frontal bone is the one that forms the forehead and also contains the frontal sinuses. This bone is located at the front of the skull and is critical for protecting the frontal lobe of the brain. The frontal sinuses, which are air-filled spaces within the frontal bone, play a role in reducing the overall weight of the skull and may also assist in resonance during speech.

The other bones mentioned do not serve these functions. The zygomatic bone, for instance, is more associated with the cheek area and does not contribute to the forehead structure or house sinuses. The nasal bone primarily forms the bridge of the nose and does not contain any sinuses. The temporal bone is located on the sides and base of the skull, with functions related to forming parts of the ear and the side wall of the cranium, rather than contributing to the forehead or housing sinuses.
