"location: within the external fascia of the pharynx 3, mainly over the middle pharyngeal constrictor on the posterolateral wall of the pharynx 4"
"origin and course: it is formed from the union of branches from the vagus nerve, glossopharyngeal nerve and cervical sympathetic nerves 4,5"
"supplies the superior, middle and inferior pharyngeal constrictor muscles, palatopharyngeus, salpingopharyngeus, levator veli palatini, palatoglossus and the muscle of the uvula 4,5"
"supplies the superior, middle and inferior pharyngeal constrictor muscles, palatopharyngeus, salpingopharyngeus, levator veli palatini, palatoglossus and the muscle of the uvula 4,5"
"The superior, middle and lower pharyngeal constrictor muscles, palatopharyngeus, salpingopharyngeus, levator veli palatini, palatoglossus and the muscle of the uvula are all innervated by branches of the pharyngeal plexus 1-5. The innervations of levator veli palatini and uvular muscle remain controversial 11-13. The levator veli palatini muscle has been reported by varying sources to receive its nerve supply solely through the pharyngeal plexus or doubly through the pharyngeal plexus and branches of the facial nerve 11-13. The muscle of the uvula has been reported to receive both dual innervation from the pharyngeal plexus and lesser palatine nerve, and also sole innervation from either nerve 12. No consensus exists."

"Sympathetic fibres are supplied from the superior cervical ganglion via branches from the plexus on the external carotid artery; this element is vasoconstrictor 4."
