What is the cranial fossa?

cranial fossa is a small depression or cavity in the skull, which is part of the human skull where the brain is located. There are three types of cranial fossae: front, medium and rear skull fossa. These three holes are located on the skull base.

Cranial fossae - plural spelling cranial fosms - are part of the intracranial cavity, which is the exact space where the brain is placed. The membrane -called meninges system lines the brain while floating on a protective, pure, colorless liquid called cerebrospinal fluid. The intracranial cavity consists of the fusion of eight bones: two parietal and two time bones and ethmoid, frontal, occipital and sphenoid bones.

The front skull fossa is the highest of the skull fossae. Horizontal front bone plates, CribriForm plates Ethmoid bone and smaller wings, and the front of the sphenoid bone forms the floor of the front skull fossa. Anothering Hollow is browsing through three stitches, which are fibrous joints that are found only in the skull. They are a queoethmoid stitch thatIt is located behind the ethmoid bone and the front bone; Sphenoetmoid stitch, which comes between sphenoid bone and ethmoid bone; and the sphenophrontal stitch located between the sphenoid bone and the front bone.

Medium cranial fossa is separated from the front skull fossa using a sphenoid bone. It is deeper than its frontal counterpart, but it shrinks in the middle and extends laterally to the sides of the skull. Most of the fossa bindings consist of smaller sfenoid bone wings and chiasmatic grooves that bind its superior surface. Sphenoparietal, sphenoptrosal, sphenosquamosal and squamosal stitches pass through medium fossils. This fossa is responsible for supporting temporary brain lobes, which prompt part of the leaf of nerve tissue outside the anterior brain known as the cortex.

The rear skull fossa is thus named because it is the highest of the three skulls. Is separated from the middle channel by depression called Clivus and part of the timeBones known as Petrous Crest. The ochitital bone closes it from the back and its walls consist of parts of the time bone. It is responsible for the content of the brain stem, especially the lower half of the brain stem known as Medulla Oblongata and the bridge above it called pony. It also contains the brain of the brain.
