| 11. | He gave a good description of the sphenoid sinus in an adult, but denied its existence in children.
|
| 12. | One difficulty was the scarcity of sphenoid bones, which are fragile and often are not preserved in skull fossils.
|
| 13. | The upper head originates from the infratemporal surface and the infratemporal crest of the greater wing of the sphenoid bone.
|
| 14. | He was the first anatomist to publish descriptions of satisfactory pterygoid process and the sphenoid bone and bone clinoideo tear.
|
| 15. | In mammals, these various bones are often ( though not always ) fused into a single structure; the sphenoid.
|
| 16. | Crossing the under surface of the sphenoid, the sphenopalatine artery ends on the nasal septum as the posterior septal branches.
|
| 17. | Adenomas greater than 10mm ( macroadenomas ) can cause remodeling of the underlying sphenoid bone altering the shape of the sella turcica.
|
| 18. | Zack finds that the ethmoid and sphenoid fragments do not fit together, which Brennan suspects is due to a degenerative disease.
|
| 19. | She has studied changes in the sphenoid bone in the skull closely linked to the embryonic process of neurulation and neural crest migration.
|
| 20. | The lateral wall is formed by the frontal process of zygomatic and more posteriorly by the orbital plate of the greater wing of sphenoid.
