Behind the foramen magnum is a longitudinal ridge, which givesattachment to the falx cerebelli, and divides the two inferior fossasofthe occipital bone; and above the ridge is the internal occipital pro-tuberance and the transverse groove lodging the lateral sinus. The external surface of the base of the skull is extremely irregu-lar. From before backwards it is formed by the palate processes ofthe superior maxillary and palate bones; the vomer; pterygoid, spi-nous processes, and part of the body of the sphenoid; under surfaceof the squamous, petrous, and mastoid portion of the temporals; andby the occipital bone. The palate processes of the superior maxil-lary and palate bones constitute the hard pala
