The sphenoid bone is located in the center of the cranial base Figures 10-3 and 10-5. 345 The intimate contact of the body of the sphenoid bone with the nasal cavity below and the pituitary gland above has led to the transsphenoidal route being the operative approach of choice for most sellar tumors. Greater wing of sphenoid bone.

Sphenoid bone upper surface. Sphenoid bone anterior and inferior surfaces. The greater wing of the sphenoid bone or alisphenoid is a bony process of the sphenoid bone.

There is one on each side extending from the side of the body of the sphenoid and curving upward laterally and backward. The sphenoid bone forms the rostral base of the cranial cavity. It is composed of the rostral presphenoid bone that in the cat but not in the dog contains the sphenoid sinus and the caudal basisphenoid bone.

The chiasmatic fossa is located on the superior surface of these bones and is the anatomical site of the optic chiasm. The Sphenoid Bone is an unpaired bone of the neurocranium.

Floor of the skull. Identify the region of the sphenoid bone in contact with the pituitary gland. Identify the region of the sphenoid bone that contains the optic canal.

Which of the following foramen convey a branch of. Diagnostic difficulties in the diagnosis of sphenoid bone dysplasia are due not only to the rare location of lesions wi-thin this anatomical region but also to the high diversity of CT and MRI scans due to varied proportions between fibrous and bone tissue in the involved bones. In MRI scans fibrous.
