| musculus constrictor pharyngis medius | Origin, stylohyoid ligament, lesser cornu of the hyoid bone (chondropharyngeal part) and greater cornu of the hyoid bone (ceratopharyngeal part); insertion, pharyngeal raphe in the posterior wall of the pharynx; action, narrows pharynx in the act of swallowing; nerve supply, pharyngeal plexus. Synonym: musculus constrictor pharyngis medius. (05 Mar 2000) |
| musculus constrictor pharyngis superior | 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) |
| Mycoplasma pharyngis | A species occurring as a commensal in the human oropharynx. (05 Mar 2000) |
| tela submucosa pharyngis | The fibrous coat of the pharyngeal wall situated between the mucous and muscular coats; it is attached above to the basilar part of the occipital bone, and the petrous part of the temporal bone. This layer and the mucosa which lines it forms the wall of the non-muscular pharynx (pharyngeal vault) above the superior pharyngesl constrictor muscle. Synonym: fascia pharyngobasilaris, aponeurosis pharyngea, tela submucosa pharyngis. (05 Mar 2000) |
| tunica mucosa pharyngis | The mucous coat of the pharynx. Synonym: tunica mucosa pharyngis. (05 Mar 2000) |
| tunica muscularis pharyngis | Muscular layer of the pharyngeal wall. In contrast with the muscular coats of the rest of the gastrointestinal tract (except anal canal), that of the pharynx has an outer circular layer and an inner longitudinal layer. Synonym: tunica muscularis pharyngis. (05 Mar 2000) |
| lacuna pharyngis | A depression near the pharyngeal opening of the auditory (eustachian) tube. (05 Mar 2000) |
| fornix pharyngis | The non-muscular upper end of the nasopharynx where the pharyngeal mucosa is firmly applied to the body of the sphenoid bone and to pharyngobasilar fascia. Synonym: fornix pharyngis. (05 Mar 2000) |
