The sphenopalatine foramen is situated posterior to the middle nasal meatus orbital process of palatine bone, anterior to the sphenoidal process of palatine bone, inferior to the body and concha [clarification needed] of the sphenoid bone, and superior to the superior margin of the perpendicular plate of palatine bone. [1]
The sphenopalatine foramen, large and oval-shaped, is above the back of M 4. The optic canal is small, has a primitive form of opening in front of the pterygoid crest, and is separated from it by a thick bony wall except in the cases of P. lautricense and P. duvali .
Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening between the venous and arterial sides of the fetal heart Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels
the maxillary nerve (CN V 2, the second division of the trigeminal nerve), with which is the nerve of the pterygoid canal, a combination of the greater petrosal nerve (preganglionic parasympathetic) and the deep petrosal nerve (postganglionic sympathetic). To obtain block anesthesia of the entire second division of the trigeminal nerve, an ...
The sphenopalatine artery is the artery commonly responsible for epistaxis (difficult to control bleeding of the nasal cavity, especially the posterior nasal cavity). [3] In severe nose bleed cases which do not stop after intense packing of anti-clotting agents, the sphenopalatine artery can be ligated (clipped and then cut) during open surgery ...
The anterior border forms the posterior boundary of the sphenopalatine notch. [1] The posterior border, serrated at the expense of the outer table, [citation needed] articulates with the vaginal process of the medial pterygoid plate of sphenoid bone. [1] The medial border articulates with ala of vomer. [1]
