Study Notes
Skull and Intracranial Fossae Overview
- The cranial cavity floor features three distinct depressions, known as cranial fossae.
- Each fossa accommodates different parts of the brain.
Anterior Cranial Fossa
- Most shallow and superior fossa among the three.
- Located above the nasal and orbital cavities.
- Houses part of the frontal lobe of the brain.
Middle Cranial Fossa
- Centrally positioned and shaped like a butterfly.
- The central section accommodates the pituitary gland.
- Lateral parts provide space for additional brain structures.
Posterior Cranial Fossa
- Deepest and most posterior of the cranial fossae.
- Accommodates the brain stem and cerebellum.
