Video - Nasal cavity and larynx histology

The nasal cavity is the hollow space in the head that is connected to the exterior of the body through the nostrils; and the larynx also known as the voicebox is a muscular organ located in the neck that is responsible for producing sound. The histology of the nasal cavity and larynx refers to the structure and function of the cells and tissues that make up these organs.

The nasal cavity is mainly lined with respiratory epithelium, which consists of pseudostratified ciliated columnar cells with goblet cells. But the roof of the nasal cavity will have olfactory epithelium instead, which has a significantly thicker epithelium with modified cilia that function as olfactory receptors.

The Larynx consists of two folds: the vestibular folds and the vocal folds. The vestibular folds are primarily respiratory epithelium and have a large number of seromucous glands; while the vocal folds have respiratory epithelium as well, and stratified squamous epithelium that covers the vocalis ligament.
