OROPHARYNX
|
B. Oropharynx
1. Extends from the soft palate to the superior border ofthe epiglottis; its lateral and posterior walls are formed by the pharyngeal constrictors, and its anterior wall is formed by the posterior part ofthe tongue infe- riorly, and opens into the faucial isthmus superiorly |
|
|
FAUCIAL ISTHMUS
-what does it connect? -bounded by? |
2. Faucial isthmus
a. Region connecting tlie oropharynx with the oral cavity; it is bounded by the palatopharyngeal and palatoglossal arches and contains the palatine tonsils |
|

FAUCIAL ISTHMUS
PALATOPHARYNGEAL ARCH |
2. Faucial isthmus
b. Palatopharyngeal arch: posterior arch formed by a pair of folds ex- tending from tlie soft palate to the lateral pharyngeal wall; each fold contains a palatopharyngeus muscle |
|

FAUCIAL ISTHMUS
PALATOGLOSSAL ARCH |
2. Faucial isthmus
c. Palatoglossal arch: anterior arch formed by a pair of folds extend- ing from the soft palate to the sides ofthe tongue; each fold contains a palatoglossus muscle |
|
|
FAUCIAL ISTHMUS
PALATINE TONSILS |
2. Faucial isthmus
d. Palatine tonsils: located laterally within the faucial isthmus, between the palatopharyngeal and palatoglossal arches; they are prominent in children but involuted in the adult |

LARYNGOPHARYNX
-extends from? -lateral and posterior walls? -anterior wall opens into? -inferiorly how is the anterior wall formed? |
. Laryngopharynx
1. Extends from the superior border ofthe epiglottis to the esophagus; its lateral and posterior walls are formed by the middle and inferior pha- ryngeal constrictors and its anterior wall opens into the laryngeal aditus superiorly and, inferiorly, is formed by the mucosa covering the poste- rior aspect ofthe larynx and tlie mucosa lining the piriform recesses, depressions on either side ofthe larynx |

PHARYNGEAL CONSTRICTORS
SUPERIOR PHARYNGEAL CONSTRICTOR ORIGIN |
1. Superior pharyngeal constrictor
a. Origin: side ofthe tongue and the pterygomandibular raphe; the pterygomandibular raphe extends from the pterygoid hamulus to the posterior end of the mylohyoid line and represents the region of interdigitation of muscle fibers ofthe superior pharyngeal constric- tor and buccinator |

PHARYNGEAL CONSTRICTORS
SUPERIOR PHARYNGEAL CONSTRICTOR INSERTION |
