Sphenoidal process of palatine bone

The sphenoidal process of the palatine bone is a thin, compressed plate, much smaller than the orbital, and directed upward and medialward.
It presents three surfaces and two borders.
The orbital and sphenoidal processes are separated from one another by the sphenopalatine notch. Sometimes the two processes are united above, and form between them a complete foramen, or the notch may be crossed by one or more spicules of bone, giving rise to two or more foramina.
