The squamous part is the anterior superior portion of the temporal bone that forms the lateral part of the middle cranial fossa.It has the appearance of a large flattened plate. Its external surface is smooth and slightly convex. Above the external acoustic meatus, there is a groove on the external surface of the bone for the middle .

The posterior cranial fossa is the most posterior aspect of the skull base housing the brainstem and cerebellum. Gross anatomy. The following structures are present from anterior to posterior: internal acoustic meatus; foramen magnum; groove for superior petrosal sinus; jugular foramen; hypoglossal canal; vestibular aqueduct; condyloid .The posterior cranial fossa is a significant region in the lower part of the cranial cavity. This area is home to important structures like the brainstem and cerebellum.The posterior cranial fossa has specific boundaries. The back of this fossa is formed by the squamous part of occipital bone, extending up to the grooves for transverse sinuses. Towards the .A cranial fossa is formed by the floor of the cranial cavity. There are three distinct cranial fossae: Anterior cranial fossa (fossa cranii anterior), housing the projecting frontal lobes of the brain; Middle cranial fossa (fossa cranii media), separated from the posterior fossa by the clivus and the petrous crest housing the temporal lobeThe Posterior Cranial Fossa. Anatomy Video Lectures. The anterior cranial fossa is the most shallow and superior of the three cranial fossae. It lies superiorly over the nasal and orbital cavities. The fossa accommodates the anteroinferior portions of the frontal lobes of the brain.

The middle cranial fossa consists of a central portion, which contains the pituitary gland, and two lateral portions, which accommodate the temporal lobes of the brain. Both parts of the fossa are marked by numerous bony landmarks, which will be discussed below. The skull base comprises parts of the frontal, ethmoid, sphenoid, occipital and temporal bones. The facial skeleton is referred to as all skull bones anteroinferior to the cranial cavity. Prominent representatives are the . This will include the various foramina, the nerves and arteries that pass through them, but also the structures of the brain and cerebellum, which all lie within the three main parts of the skull base called cranial fossae. The anterior cranial fossa is a depression located in the front part of the skull, just behind the forehead and above the nose. It is one of three cranial fossae, or hollow areas, found in the skull and is responsible for housing and protecting the front part of the brain, including the frontal lobes and the optic nerves. Structure. The anterior cranial fossa is located at the front of the skull and is formed by the frontal bone and the ethmoid bone. It contains the frontal lobes of the brain and the orbits, or eye sockets.
