Where the frontal bone sits in the skeleton
The frontal bone is the bone of the forehead, which also forms the roof of each eye socket. It encloses the front of the brain. It meets the two parietal bones behind at the coronal suture, and inside the bone behind the eyebrows lie the air-filled frontal sinuses.
Frequently asked questions
Which part of the skeleton is the frontal bone in?
The frontal bone is one of the bones of the skull and hyoid. This group covers the bones that enclose the brain, the bones that frame the face, and the hyoid at the front of the neck.
How many bones are in the skull?
The skull has 22 bones: eight cranial bones that enclose the brain and fourteen facial bones that frame the face. The hyoid in the front of the neck is a separate bone that forms no joint with any other bone.
Is there one frontal bone or a pair?
There is just one frontal bone, on the midline of the body.
Is there a hollow space inside the frontal bone?
Yes. Behind the eyebrows the bone holds the frontal sinuses, air spaces that open into the nasal cavity. They are one of the paranasal sinuses.
