    The sphenopalatine foramen is a foramen of the skull that connects the nasal cavity and the pterygopalatine fossa. It gives passage to the sphenopalatine artery , nasopalatine nerve , and the superior nasal nerve (all passing from the pterygopalatine fossa into the nasal cavity).

  3. Posterior septal artery - Wikipedia

    en.wikipedia.org/wiki/Posterior_septal_artery

    The posterior septal artery passes through the sphenopalatine foramen to enter the nasal cavity. [2] To enter the posterior border of the nasal septum, the posterior septal artery travels along the anterior wall of the sphenoid sinus passing by the sphenoid ostium and choana. [ 1 ]

    It is the indented area medial to the pterygomaxillary fissure leading into the sphenopalatine foramen. It communicates with the nasal and oral cavities, infratemporal fossa, orbit, pharynx, and middle cranial fossa through eight foramina. [2]

    The sphenopalatine artery passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus.Here it gives off its posterior lateral nasal branches which spread forward over the conchæ and meatuses, anastomose with the ethmoidal arteries and the nasal branches of the descending palatine, and assist in supplying the frontal, maxillary, ethmoidal, and ...

  7. Nasal meatus - Wikipedia

    en.wikipedia.org/wiki/Nasal_meatus

    From behind, the sphenopalatine foramen opens into the cavity of the superior meatus and the meatus communicates with the posterior ethmoidal cells. Above and at the back of the superior concha is the sphenoethmoidal recess which the sphenoidal sinus opens into. The superior meatus occupies the middle third of the nasal cavity’s lateral wall.

  8. Sphenopalatine artery - Wikipedia

    en.wikipedia.org/wiki/Sphenopalatine_artery

    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 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.
