ANT334H5 Lecture Notes - Lecture 3: Foramen Rotundum, Chiasmatic Groove, Vomer
Document Summary
Sella turcica the pituitary sits here; saddle-like. Dosum sellae the back of the saddle. Tuberculum sellae - anterior portion of the sella turcica. Clinoid process holds the pituitary (anterior, posterior. Chiasmatic groove a. k. a optic groove (this runs between the two holds) Superior orbital fissure separates the greater and lesser wings. Foramen rotundum allow vessels to run in an anterior posterior direction: this is for the maxillary branch of the trigeminal cranium nerve. Foramen ovale have the mandibular branch of the trigeminal cranium nerve. Formen spinosum is for the middle meningeal blood vessels. Formen lacerum articulation of the sphenoid, occipital and l+r temporal. Lateral pterygoid plate - the outside of the legs on the sphenoid. Medial pterygoid plate (the point on this is the hamulus) Pterygoid fossa (ptergoid notch) it is the space between the medial and later pterygoid plate. Crista galli like the fin (comes out of the ethmoid)
