pharyngeal plexus การใช้

• Note that the intrinsic muscles of the larynx are innervated by the vagus nerve but not by the pharyngeal plexus.
• These muscles are innervated by the pharyngeal plexus via the vagus nerve, with the exception of the tensor veli palatini.
• Receptors initiating this reflex are proprioceptive ( afferent limb of reflex is IX and efferent limb is the pharyngeal plexus-IX and X ).
• Other sources state that the palatoglossus is not innervated by XI hitchhiking on X, but rather it is innervated by IX via the pharyngeal plexus formed from IX and X.
• The external laryngeal nerve gives branches to pharyngeal plexus and the superior portion of the inferior pharyngeal constrictor, and communicates with the superior cardiac nerve behind the common carotid artery.
• It passes across the internal carotid artery to the upper border of the Constrictor pharyngis medius, where it divides into numerous filaments, which join with branches from the glossopharyngeal, pharyngeal plexus.
