Study Notes
Pharynx
- The pharynx is located behind the nose and connects to the nasal cavities
- It has respiratory epithelium and contains the medial pharyngeal tonsil, which is part of the immune system
- The medial pharyngeal tonsil helps detect and fight germs and other harmful substances
- The pharynx also contains auditory tubes that connect the nasopharynx to the middle ear cavities
- Auditory tubes help equalize pressure between the ears and outside environment and drain fluids to keep the ears healthy
Oropharynx
- The oropharynx is located behind the mouth and has stratified squamous epithelium
- The oropharynx is a part of the throat
Larynx
- The larynx is a short passageway between the pharynx and trachea
- It has walls made of sturdy hyaline cartilage and reinforced by smaller elastic cartilage
- The larynx maintains an open airway and helps in making sound by movement of its cartilages by skeletal muscle
- The lining of the larynx forms two pairs of folds: the vestibular fold and the vocal cords
- The vestibular fold helps protect the airway, and the vocal cords are essential for sound production
- The epiglottis is a flat structure above the larynx that acts like a lid to prevent swallowed food or fluid from entering the airway
Trachea
- The trachea is lined by respiratory epithelium that contains seromucous glands that moisten the windpipe
- It is reinforced by a series of C-shaped rings made of hyalin cartilage
- The trachealis muscle relaxes during swallowing to allow the esophagus to bulge into the tracheal lumen
- The trachealis muscle contracts strongly during the cough reflex, narrowing the tracheal lumen and increasing the velocity of expelled air
Pharynx

- It has respiratory epithelium and contains the medial pharyngeal tonsil, which is part of the immune system
