The base of the skull is a complex structure that forms the floor of the cranial cavity, housing critical neurovascular pathways and supporting the brain's weight. This anatomical illustration provides both external and internal views, highlighting the intricate arrangement of bones like the sphenoid, temporal, and occipital, along with key foramina and fossae. These views reveal the skull base's role in separating the cranial fossae and facilitating communication between the brain and the body.

The superior view of the base of skull provides a detailed perspective on the cranial floor, revealing the intricate arrangement of bones and foramina that support the brain and facilitate neurovascular communication. This anatomical illustration highlights the frontal, ethmoid, sphenoid, temporal, and occipital bones, with key features like the lesser wing of the sphenoid and the petrous ridge separating the cranial fossae. Understanding this view is essential for comprehending how the skull base protects the brain and supports critical physiological functions.
