    f H '} OS FRONTIS Os Frontale. The frontal bone is fituated in the anteiior part of the fkull, forming the foi'ehead and upper part of the orbits ; it is of a fernici;cu'ar 0;ape, and when defached from the other bones of the cranium has fome refemblance to a cockle-niell. Exter- nally, where it forms the forehead, it is very imooth and convex ; but below, where it affifts m forming the orbit, it affords feveral procefTes and cavities. The inner and concave furface of this bone is turned towards the brain, and in the centre of its inferior part is the ethmoid bone, which is placed at the top of the cavity of the noftrils. It fometimes -conilfts of two portions, in confequence of the fagittal future being continued down through its middle to the nofe. This is more frequent in females than males. Processes. Tv^ofrontal eminences, which mark the centres of offification; —twoyr(7/?/a//K^frf/?//V,f, which are fituated over the frontal finufes;—ivfO fupercUiary rniges or arches, which give origin to the frontal mufcles, and whofe extremities are called the angular or orbitar procefTes; behind each external angular procefs the furface of the bone is confiderably depreffed, for the iituation of a part of the temporal mufcle ;—an external frontal ^?W, upon which the olTa nafi reft;—an internal frontal fphie,to which the dura mater adheres ;—and two orbitar plates, which feparate the orbits from the cavity of the cranium. Cavities. 1 he cerebralca^vity, which contains the anterior portions of the hemifpheres of the brain;—a large notch between the orb:':ar plates for the fituation of the cribriform plate of the ethmoid bone ;—two frontal ox pituitary fnufes within the bone, above the root of the nofe; they arc always leparated by a thin bony partition J and open by two fmall holes into the noftrils^ 5
