Sphenopalatine artery

from Wikipedia, the free encyclopedia

The sphenopalatine artery (sphenoid-palate artery) is a blood vessel of the head. It arises from the end section of the maxillary artery in the pterygopalatine fossa and runs through the sphenopalatine foramen of the palatine bone - together with the vein of the same name and the nasal branches ( rami nasales , in animals called the caudal nasal nerve ) of the pterygopalatine nerve - into the nasal cavity .

The sphenopalatine artery supplies large parts of the nasal cavity, including the vascularized area of ​​the nasal septum ( Locus Kiesselbachi ), which is particularly often the starting point for nosebleeds . If necessary, the artery can be tied off if there is excessive nosebleed.
