Respiratory Epithelium - pseudostratifed columnar epithelium with cilia and goblet cells. Pseudostratified Columnar Cells - basal bodies visible as a dark line at the base of the cilia.

 

The epiglottis closes the larynx preventing inspired air from entering the esophagus and aspiration of food and liquids into the trachea. The larynx contains vocal folds or true vocal cords and vestibular folds or false vocal cords that produce sounds and resonance respectively.

 

The mucous membrane of the larynx is mostly covered by multi-rowed cylindrical epithelium with cilia . A regular exception is the plicae vocales and part of the surface of the epiglottis where the epithelium is multi-layered squamous non-keratinized .

 

The larynx is a short epithelium-lined tube formed by nine pieces of cartilage and several ligaments that bind them together. It is located along the body's midline in the neck region deep to the skin and the muscles of the neck and anterior to the esophagus and cervical vertebrae.

 

The document presents a detailed histological overview of the pharynx and larynx highlighting their structure and components. The pharynx is divided into the nasopharynx oropharynx and laryngopharynx each possessing distinct histological features such as epithelial types and connective tissue.

 

Larynx Pseudostratified columnar ciliated epithelium with seromucous glands in its lamina propria (laryngeal mucosa) continues in to the larynx and covers the false vocal fold and the end of the laryngeal ventricle (a depression between the false vocal fold and the true vocal cord).
