What is the ascending pharyngeal artery a branch of?
the external carotid artery
The ascending pharyngeal artery, the smallest branch of the external carotid artery, is a long, slender vessel, deeply seated in the neck, beneath the other branches of the external carotid and under the stylopharyngeus.
What does the ascending pharyngeal artery supply?
The ascending pharyngeal artery is a small but important artery that supplies multiple cranial nerves and anastomotic channels to the anterior and posterior cerebral circulations. Several disease processes in the head and neck involve the ascending pharyngeal artery.
Which artery gives off the ascending pharyngeal artery?
External carotid artery
It lies just superior to the bifurcation of the common carotid arteries. The artery most typically bifurcates into embryologically distinct pharyngeal and neuromeningeal trunks….

Where is ascending palatine artery?
The ascending palatine artery most commonly originates from the facial artery and runs alongside the pharynx and passes between the styloglossus and the stylopharyngeus muscles. Its location is with the levator veli palatini where it divides into two branches to supply the soft palate and palatine glands.
What does the ascending palatine artery supply?
The ascending palatine artery is a branch of the facial artery that supplies part of the soft palate. In addition, the vessel also supplies the tensor veli palatini, uvular muscle, palatine tonsils, and palatopharyngeus 1,2. The posterior branch supplies the posterior and inferior soft palate especially 2.
What are the branches of maxillary artery?
Five branches, each of which enters a bony foramen:
- deep auricular artery (enters squamotympanic fissure)
- anterior tympanic artery (enters squamotympanic fissure)
- middle meningeal artery (enters foramen spinosum)
- accessory meningeal artery (enters foramen ovale)
- inferior alveolar artery (enters mandibular foramen)
What are the branches of facial artery?
The branches of the facial artery are:
- cervical. Ascending palatine artery. Tonsillar branch. Submental artery. Glandular branches.
- facial. Inferior labial artery. Superior labial artery. Lateral nasal branch to nasalis muscle. Angular artery – the terminal branch.
What are the major branches of the internal carotid artery?
Branches:
- Posterior communicating artery.
- Anterior chorodal artery.
- Anterior cerebral artery.
- Middle cerebral artery.
What are the two branches of the internal carotid artery?
Along its course, the internal carotid artery gives rise to many branches, ultimately dividing into its two terminal ones called the anterior and middle cerebral arteries.
What is the greater palatine artery branch of?
descending palatine artery
The greater palatine artery is a branch of the descending palatine artery (branch of the 3rd part of the maxillary artery) 4. The blood vessel supplies the hard palate mucosa, gingival tissue, and palatine tonsils 5.
What are the 5 branches of the maxillary artery?
Why is the ascending pharyngeal artery so important?
Summary: Neuroradiologists generally do not fully appre- ciate the importance of the territory of the ascending pha- ryngeal artery. The ascending pharyngeal artery is a small but important artery that supplies multiple cranial nerves and anastomotic channels to the anterior and posterior cerebral circulations.
Where does the hypoglossal division enter the pharyngeal artery?
The hypoglossal division enters through the hypoglossal canal, supplies CNXII, and vascularizes the adjacent dura. It has rich anastomotic networks with branches of the meningohypohyseal trunk and middle meningeal artery. The jugular division enters thru the jugular foramen and runs poserolaterally.
Where does the pharyngeal branch reach the soft palate?
The pharyngeal branches reach the soft palate by coursing inferiorly between the superior pharyngeal constrictor and levator veli palatini muscles. They supply the pharyngeal constrictors, stylopharyngeus, soft palate, palatine tonsil, and pharyngotympanic (Eustachian) tube.
Is the pharyngeal trunk or The neuromeningeal trunk?
Here, the “pharyngo-occipital” only supplies the pharyngeal trunk (top images). The neuromeningeal trunk (white arrows) comes off more proximally, at takeoff of the occipital (bottom images). Notice that it is the neuromeningeal trunk and not occipital that opacifies the vertebral artery (black arrow).
