Study Notes
The Viscerocranium – Facial Skeleton
- The floor of the Cranial cavity is divided into three distinct depressions known as:
- The Anterior Cranial Fossa
- The Middle Cranial Fossa
- The Posterior Cranial Fossa
- Each fossa accommodates a different part of the brain
Anterior Cranial Fossa
- The most shallow and superior of the three cranial fossae
- Lies superiorly over the nasal and orbital cavities
- Accommodates part of the frontal lobe of the brain
Middle Cranial Fossa
- Located centrally in the cranial floor
- Butterfly shaped
- Middle part accommodates the pituitary glands
- Two lateral parts accommodate the temporal lobes of the brain
Posterior Cranial Fossa
- The deepest and most posterior of the three cranial fossae
- Accommodates the brain stem and the cerebellum
