Document Summary
Identify and briefly describe the internal bony landmarks of the cranial cavity. a. 3) frontal crest - partial attachment of falx cerebri sagittal sulcus - associated with the superior sagittal sinus depressions for arachnoid granulations (granular foveolae) - the superior arachnoid granulations lie mainly along the sides of the sagittal sinus. They represent areas of absorption of cerebrospinal fluid (csf) orbital plates - comprise the floor of the anterior cranial. 4) (and the roof of the orbital cavity). [2) crista galli - also a point of attachment of the falx cerebri superior and middle conchae - lateral walls of the nasal. [4) cribriform plate - the perforated bone through which fibers of the olfactory n. (c. n. I) pass on their way upward from the superior part of the nasal cavity. perpendicular plate - forms the upper part of the nasal ethmoidal air cells]
