The frontal bone is one of the flat cranial bones that forms the forehead and roof of the orbits. The frontal bone also forms the upper part of the nasal cavity as well as forming the floor of the skull, where the brain is housed. Two cavities, the frontal sinuses, lie within the frontal bone, just behind the spots above each orbit. The frontal bone is attached to the parietal bones by the coronal suture, and is also connected by sutures to the sphenoid, ethmoid bone, maxillary, nasal, lachrymal, and zygomatic bones. In the center of the front of the frontal bone, just between and slightly above the orbits, is a raised portion of the bone, called the glabella. The frontal bone also features two foramina. one just above each orbit. Research Frontal Bone
