Floor Aspect Skull

The skull is a bony structure that supports the face and forms a protective cavity for the brain.
Floor aspect skull. The sella turcica latin for turkish seat is a saddle shaped depression in the body of the sphenoid bone of the human skull and of the skulls of other hominids including chimpanzees orangutans and gorillas it serves as a cephalometric landmark the pituitary gland or hypophysis is located within the most inferior aspect of the sella turcica the hypophyseal fossa. The same patient with the possible basilar skull fracture requires a frontal projection of the skull. The right and left medial pterygoid plates form the posterior lateral walls of the nasal cavity. The physician wants the projection to demonstrate the frontal bone and place the petrous ridges in the lower 1 3 of the orbits but it has not been determined whether the patient s cervical spine has been fractured so the patient cannot be moved from a supine position.
The floor is flattened from before backward and concave from side to side. The floor of the sella turcica which in most cases is concave may be flat or even convex bruneton et al 1979. It is formed by the palatine process of the maxilla and the horizontal part of the palatine bone. This anatomic region is complex and poses surgical challenges for otolaryngologists and neurosurgeons alike.
These are the medial pterygoid plate and lateral pterygoid plate pterygoid wing shaped. These joints fuse together in adulthood thus permitting brain growth during adolescence. On the inferior aspect of the skull each half of the sphenoid bone forms two thin vertically oriented bony plates. The floor consists of the frontal bone ethmoid bone and the anterior aspects of the body and lesser wings of the sphenoid bone by teachmeseries ltd 2020 fig 1 the bones of the base of the skull.
The skull base forms the floor of the cranial cavity and separates the brain from other facial structures. Near its anterior end is the opening of the incisive canal. An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall typically resulting from impact of a blunt object larger than the orbital aperture or eye socket most commonly the inferior orbital wall i e. It is comprised of many bones formed by intramembranous ossification which are joined together by sutures fibrous joints.
The floor is likely to collapse because the bones of the roof and lateral walls are robust. The cranium skull is the skeletal structure of the head that supports the face and protects the brain it is subdivided into the facial bones and the brain case or cranial vault figure 1 the facial bones underlie the facial structures form the nasal cavity enclose the eyeballs and support the teeth of the upper and lower jaws.
