Ostium Bursae

Pharyngeal bursa. [Bursa pharyngealis]. Blind pouch in the roof of the pharynx; it is more frequently present in children, less often in adults. A

Pharyngeal opening of auditory tube. Ostium pharyngeum tubae auditivae (auditoriae). Opening found in the nasopharynx. A Torus tubarius. Elevation produced by the dor-somedial cartilage of the auditory tube posterior to the tube opening. A

Salpingopharyngeal fold. Plica salpingopharyngea. Mucosal fold overlying the salpingopharyngeal muscle and extending obliquely downward from the dorsomedial lip of the auditory tube cartilage. A

Torus levatorius. Elevation situated in front of the dorsomedial lip of the cartilage of the auditory tube and below the tube opening. It overlies the levator veli palatini muscle. A Tubal tonsil. Tonsilla tubaria. Submucosal lymphatic tissue near the opening of the auditory tube.

Pharyngeal recess. Recessus pharyngeus [[Rosenmuller's]]. Lateral recess of the na-sopharyngeal space behind the auditory tube. A Oropharynx. Pars oralis pharyngis. The portion of the pharyngeal cavity located behind the oral cavity. See p. 117. E

Vallecula epiglottica. Fossa between the median and lateral glossoepiglottic folds. B Median glossoepiglottic fold. Plica glos-soepiglottica mediana. Unpaired mucosal fold located in the median plane between the base of the tongue and the epiglottis. B Lateral glossoepiglottic fold. Plica glos-soepiglottica lateralis. Bilateral mucosal fold between the base of the tongue and the epiglottis. B Laryngopharynx. Pars laryngea pharyngis. The portion of the pharyngeal cavity situated behind the larynx. See p. 117. E

Piriform recess. Recessus piriformis. Channel between the aryepiglottic fold and the thyrohyoid membrane or thyroid cartilage. B Plica nervi laryngei. Mucosal fold in the pir-iform recess produced by the underlying internal branch of the superior laryngeal nerve and the superior laryngeal artery. B Pharyngobasilar fascia. Fascia pharyn-gobasilaris. Membranous wall of the uppermost muscle free portion of the pharynx. It corresponds to the thickened tela submucosa. C D E Submucosa. Tela submucosa. Connective tissue layer between the mucosa and muscularis. A Mucosa. Tunica mucosa. Pharyngeal mucous membrane lined by stratified squamous or pseu-dostratified ciliated columnar (nasopharynx) epithelium.

Pharyngeal glands. Gll. pharyngis. Small sub-epithelial mixed salivary glands. Muscularis of pharynx. Tunica muscularis pharyngis. Muscular layer of pharyngeal wall. A

20 Pharyngeal raphe. Raphe pharyngis. Connective tissue band between the right and left pharyngeal muscles, extending posteriorly in the mid-line. C

21 Pterygomandibular raphe. Raphe pterygomandibular. Tendinous seam between the buccinator muscle and the superior pharyngeal constrictor. It extends from the pterygoid hamulus to the mandible. D

22 Superior pharyngeal constrictor muscle. M.

constrictor pharyngis superior. Uppermost constrictor of the pharynx consisting of the four parts described below, which attach to the pharyngeal raphe. I: Pharyngeal plexus. C D

23 Pterygopharyngeal part. Pars pterygophary-nea. o: Medial plate of pterygoid process and pterygoid hamulus. D

24 Buccopharyngeal part. Parsbuccopharyngea. o: Pterygomandibular raphe. D

26 Glossopharyngeal part. Pars glossopharyngea. o: Intrinsic muscles of tongue. D

27 M. stylopharyngeus. o: Styloid process. i: Between superior and middle pharyngeal constrictors radiating into the pharyngeal wall, thyroid cartilage and epiglottis. I: Glossopharyngeal (IX) nerve. C

28 M. salpingopharyngeus. o: Dorsomedial lip of auditory tube cartilage and part of longitudinal musculature of pharyngeal wall. i: Lateral wall of pharynx. A: Prevents backward displacement of the levator veli palatini muscle. I: Pharyngeal plexus. A

29 Middle pharyngeal constrictor muscle. M. constrictor pharyngis medius. More centrally located pharyngeal constrictor arising from the hyoid bone. o: Pharyngeal raphe. I: Pharyngeal plexus. C

30 Chondropharyngeal part. Pars chondropharyn-gea. o: Lesser horn of hyoid. D

31 Ceratopharyngeal part. Pars ceratopharyngea. o: Greater horn of hyoid. D

32 Inferior pharyngeal constrictor muscle. M. constrictor pharyngis inferior. o: Larynx. I: Pharyn-geal plexus. C D

33 Thyropharyngeal part. Pars thyropharyngea. o: Oblique line of thyroid cartilage. D

34 Cricopharyngeal part. Pars circopharyngea. o: Cricoid cartilage. D

34 a Buccopharyngeal fascia. Fascia buccopharyn-

gealis. Continuation of the buccopharyngeal fascia into the loose tissue connecting the pharynx to the deep cervical fascia.

35 Peripharyngeal space. Spatium peripharyn-geum. Connective tissue space associated with the pharynx.

36 Retropharyngeal space. Spatium retropharyn-geum. The portion of the peripharyngeal space between the pharynx and the prevertebral layer of the cervical fascia. A

37 Lateropharyngeal space. Spatium latero-pharyngeum. Portion of the peripharyngeal space lateral to the pharynx.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
