Ascending pharyngeal artery

Other Terms: Arteria pharyngea ascendens, Artère pharyngienne ascendante

Description

The ascending pharyngeal artery is the smallest branch given off from the external carotid artery. It arises from the back part of that artery about one-half of an inch above the bifurcation of the common carotid artery. Sometimes, it arises from the common carotid artery. It is situated deep in the neck by the internal carotid artery and lies upon the rectus capitis anticus major muscle. It ascends between the internal carotid artery and the side of the pharynx and beneath the stylopharyngeus muscle and the glossopharyngeal nerve to the base of the skull. Here, it enters the pharynx above the superior constrictor muscle to end in the soft palate. It gives off prevertebral, pharyngeal, meningeal, palatine, and tympanic branches. The prevertebral branches are small vessels which pass outward to supply the rectus capitis anticus major and minor muscles, the sympathetic, pneumogastric, and hypoglossal nerves, and the deep cervical chain of lymphatic glands. They anastomose with the ascending cervical artery. There are three or four pharyngeal branches. They supply the upper and middle constrictor muscles, the mucous membrane of the pharynx, and the stylopharyngeus muscle. The palatine, the largest of these branches, enters the pharynx above the superior constrictor muscle and terminates in the soft palate, the auditory tube, and the tonsil. It takes the place of the ascending palatine branch of the facial artery when this vessel is small. There are three meningeal branches. They enter the cranial cavity through the jugular foramen, along with the internal jugular vein, through the anterior condyloid and middle lacerated foramina to supply the dura mater. The tympanic branch traverses the tympanic canaliculus, and along with the tympanic branch of the glossopharyngeal nerve, enters the tympanum. It anastomoses with the other tympanic arteries and supplies the adjacent structures.
