The pharynx is connected to the oral and nasal oral cavities and contains the entrances to the Eustachian tube, and the larynx (described in detail in Chapter 4. Respiratory System, Larynx). The pharynx is lined by stratified squamous epithelium. The lamina propria of the pharynx contains minor salivary glands.
The 4X micrograph presents the glands of the pharynx, the glandular soft palate forming the roof of the pharynx, and the epiglottis (the epiglottis is depicted in detail in Chapter 4. Respiratory System, Pharynx and Epiglottis 20X and 40X). The 10X micrograph shows those glandular elements in more detail, while the 20X micrograph displays the acini and duct of mucous glands present in the soft palate. The 40X micrograph shows the layers of the stratified squamous epithelium lining the pharynx.
