Anatomy

Posterior cranial fossa

Isolated view of the posterior cranial fossa as a broad, deep bowl-shaped depression on the internal base of the skull, behind the petrous temporal region. The cavity is pale ivory to off-white bone, with smooth curved concave walls and margins, deeper than the other cranial fossae. Internal bony details include subtle ridges, foramina, grooves for the venous sinuses, and prominent central opening regions, representing the space that accommodates the hindbrain structures.
