pharyngeal plexus

1. A nerve plexus along the posterior surface of the middle pharyngeal constrictor muscle. The plexus contains sympathetic, parasympathetic, and somatic (branchial) axons from the pharyngeal branch of the vagus nerve, the glossopharyngeal and external laryngeal nerves, and the sympathetic trunk. Axons from the pharyngeal plexus innervate the muscles and mucosa of the pharynx and soft palate.
2. A venous plexus that drains the pharynx and that empties into the internal jugular and facial veins; it interconnects with the pterygoid plexus.
