| sphincter constrictor cardiae | A sphincter supposedly present at the oesophagogastric junction; this is in fact an extrinsic sphincter formed by the surrounding musculature of the oesophageal hiagus of the right crus of the diaphragm; causes a normally-occuring constriction at the oesophagogastric junction observable with a barium swallow. Synonym: sphincter constrictor cardiae. (05 Mar 2000) |

| superior constrictor muscle of pharynx | Origin, medial pterygoid plate (pterygopharyngeal part), pterygomandibular raphe (buccopharyngeal part), mylohyoid line of mandible (mylopharyngeal part), and the mucous membrane of the floor of the mouth and the side of the tongue (glossopharyngeal part); insertion, pharyngeal raphe in the posterior wall of the pharynx; action, narrows pharynx; nerve supply, pharyngeal plexus. Synonym: musculus constrictor pharyngis superior, musculus cephalopharyngeus. (05 Mar 2000) |
| inferior constrictor muscle of pharynx | Origin, outer surfaces of thyroid (thyropharyngeal part) and cricoid (cricopharyngeal part, musculus cricopharyngeus; superior or upper oesophageal sphincter muscle) cartilages; insertion, pharyngeal raphe in the posterior portion of wall of pharynx; action, narrows lower part of pharynx in swallowing, the cricopharyngeal part has a sphincteric function for the oesophagus, allowing some voluntary control of eructation and reflux; nerve supply, pharyngeal plexus. Synonym: musculus constrictor pharyngis inferior, cricopharyngeus muscle, laryngopharyngeus, musculus laryngopharyngeus. (05 Mar 2000) |
| thyropharyngeal part of inferior pharyngeal constrictor muscle | thyropharyngeal part of inferior pharyngeal constrictor muscle |
| raphe pharyngis | The central line of the pharynx posteriorly where the muscular fibres meet and partly interlace. Synonym: raphe pharyngis. (05 Mar 2000) |
| pars ceratopharyngea musculi constrictoris pharyngis medii | See: middle constrictor muscle of pharynx. Synonym: pars ceratopharyngea musculi constrictoris pharyngis medii. (05 Mar 2000) |

| pars thyropharyngea musculi constrictoris pharyngis inferioris | pars thyropharyngea musculi constrictoris pharyngis inferioris |
| cavitas pharyngis | It consists of a nasal part (nasopharynx) continuous anteriorly with the nasal cavity and receiving the openings of the auditory tubes, an oral part (oropharynx) opening through the fauces into the oral cavity, and a laryngeal part (laryngopharynx) leading into the vestibule of the larynx and to the oesophagus. Synonym: cavitas pharyngis, cavum pharyngis. (05 Mar 2000) |
