Eustachian Tube connects the nasopharynx with the middle ear Function of auditory tube: ○ Equalizing the pressure ○ Draining the middle ear Oropharynx: Level of C4-C4 Bordered by Soft Palate and Epiglottis Connects with the Oral cavity through the Oropharyngeal Isthmus (Isthmus faucium) Laryngopharynx: Level of C5-C6 Continues into Larynx through Laryngeal Inlet (auditus laryngis) Piriform Fossa (Recessus Piriformis) Layers of the Pharyngeal Wall: Tunica Mucosa ○ Lined by Respiratory Epithelium (Pseudostratified epithelium with cilia and goblet cells) ○ Lined by Stratified Squamous non keratinized epithelium Tela Submucosa ○ Contains Connective tissue with blood vessels and lymph vessels, and glands Tunica Muscularis ○ Has 2 muscle layers for peristalsis ○ Internal Circular muscle layer (Stratum Circulare) ○ Outer Longitudinal Muscle layer (Stratum longitudinale) Tunica Adventitia ○ Covers Pharynx from outside External Pharyngeal Muscles: Pharyngeal Constrictors (Musculi Constrictores Pharyngis) ○ Superior Pharyngeal Constrictor ○ Medial Pharyngeal Constrictor ○ Inferior Pharyngeal Constrictor Pharyngeal Elevators (Musculi Levatores Pharyngis) ○ Stylopharyngeus Muscle (Musculus Stylopharyngeum) ○ Palatopharyngeus Muscle (Musculus Palatopharyngeum) ○ Salpingopharyngeus Muscle (Musculus Salpingopharyngeus) Sources used in this video: Memorix Anatomy 2nd Edition by Hudák Radovan (Author), Kachlík David (Author), Volný Ondřej (Author) Biorender University notes and lectures
