The medial wall is formed primarily by the orbital plate of ethmoid, as well as contributions from the frontal process of maxilla, the lacrimal bone, and a small part of the body of the sphenoid.
42.
It arises by a flat lamella from the scaphoid fossa at the base of the medial pterygoid plate, from the spina angularis of the sphenoid and from the lateral wall of the cartilage of the auditory tube.
43.
Such joints are found between the epiphyses and diaphyses of long bones, between the sphenoid, and for some years after birth, between the petrous portion of the temporal and the jugular process of the occipital bone.
44.
Dr . Fred H . Smith, a paleoanthropologist at Northern Illinois University in DeKalb, who specializes in studies of Neanderthals and other archaic hominids, said the sphenoid hypothesis " makes a lot of sense ."
45.
Its " antero-medial surface " forms, by its junction with the orbital surface of the maxilla and with the great wing of the sphenoid, part of the floor and lateral wall of the orbit.
46.
After that it attaches to the solid polyploid in the nasal cavity with a pedicle . Nasal septum, nasal turbinates, sphenoid sinus, ethmoid sinus, and hard and soft pallets are the places where killian polyps originate from.
47.
The " anterior temporal ", which is confined chiefly to the frontal bone, and opens into the sphenoparietal sinus and into one of the deep temporal veins, through an aperture in the great wing of the sphenoid.
48.
Each bone articulates in front with the ethmoid, laterally with the palatine; its pointed posterior extremity is placed above the vomer, and is received between the root of the pterygoid process laterally and the rostrum of the sphenoid medially.
49.
At the apex of the petrous part of the temporal bone the free and attached borders meet, and, crossing one another, are continued forward to be fixed to the anterior and posterior clinoid processes ( respectively ) of the sphenoid bone.
50.
Another individual, however, trained in auscultation, may be able to distinguish tympanic resonation by tapping over the sinuses, particularly the frontal sinus and ( though " much " less likely ) the sphenoid sinus, using a stethoscope.
