Document Summary
Oral pharynx is behind the uvula; inferior is just above the respiratory canal. The nasal is right behind the nasal cavity. These muscles are close to the nasopharynx and act as constrictors of the pharynx during swallowing. Innervation: vagus nerve; cn x: function: elevates the pharynx and larynx & closes the nasopharynx. Stylopharyngeus: origin: styloid process, function: elevates pharynx and larynx. Inferior constrictor: origin: circoid and thyroid cartilage, function: constricts the pharynx allowing for food to be pushed down to the. Origin: pteryoid process of the spenoid bone. As you swallow, the suprahyoid muscles are raisin and after you swallow the infrahyoid muscles are raisin. Suprahyoid: most of them are attached to the hyoid; they raise the larynx or depress the mandible (open mouth) Infrahyoid: depresses the hyoid bone and larynx during swallowing and speaking. Thyroid cartilage: spine of the open book they protect the vocal chords that are posterior to it.
