In anatomy, a fossa is a depression or hollow, usually in a bone, that can receive another articulating bone or act to support brain structures. Examples of fossae include the cranial fossa, hypophyseal fossa, temporal bone fossa, and various other fossae in different parts of the body
. Fossae are shallow depressions in the bone surface and can accommodate different anatomical structures
. For example, the middle cranial fossa is an intricate intracranial area that contains many structures susceptible to pathology, and it is described as having a "butterfly" appearance when viewed from above
. The anterior cranial fossa is the most shallow and superior of the three cranial fossae, accommodating the anteroinferior portions of the frontal lobes of the brain
