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).
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 ]
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. In the articulated skull this foramen leads from the pterygopalatine fossa into the posterior part of the superior meatus of the nose, and transmits the sphenopalatine vessels and the ...
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 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 ...
The two incisive canals usually (in 60% of individuals) have a characteristic Y-shaped or V-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa [1] as several incisive foramina.
The sphenopalatine foramen is the opening between the sphenoid bone and orbital processes of the palatine bone; it opens into the nasal cavity and gives passage to branches from the pterygopalatine ganglion and the sphenopalatine artery from the maxillary artery.
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; Greater sciatic foramen, a major foramen of the pelvis
