0 relating to the sphenoid (= a bone in the lower part of the skull) and the palate (= the top part of the inside of the mouth) --
Their palatine bones are in contact with the median; the deep sphenopalatine notch separates the pterygoids and extends forwards to between the centre of the eyes.
The roof of the fossa is perforated by large sphenopalatine vacuities.
Its roof either is wholly ossified or contains small sphenopalatine vacuities.
These blood vessels include the sphenopalatine, anterior and posterior ethmoidal arteries.
These processes are separated by the sphenopalatine notch, which is converted into the sphenopalatine foramen by the under surface of the body of the sphenoid.
The mesopterygoid fossa, the gap behind the end of the palate, is perforated by sphenopalatine vacuities, which are set far to the front.
The roof of the mesopterygoid fossa, the opening behind the palate, is not perforated by sphenopalatine vacuities.
Most of their fibers are derived from the sphenopalatine branches of the maxillary nerve.
