Nasopharynx and larynx / Носоглотка и гортань на английском языке. Лекция №30



Nasopharynx is the first part of the pharynx.
It is lined by a pseudostratified, ciliated, columnar.
Epithelium with goblet cells: under the epithelium, a gland-containing connective tissue layer rests directly on the periosteum of the bone.
The cilia beat towards the oropharynx, which is composed of a stratified, squamous, nonkeratinized epithelium.
The pharyngeal tonsil, an aggregate of nodular and diffuse lymphatic tissue, is located on the posterior wall of the nasopharynx subjacent to the epithelium. Hypertrophy of this tissue as a result of chronic inflammation results in a condition known as adenoiditis. Larynx is a passageway that connects the pharynx to the trachea and contains the voicebox. Its walls are composed of cartilage held together by fibroela-stic connective tissue.
The mucous layer of the larynx forms two pairs of elastic tissue folds that extend into the lumen. The upper pair are called the vestibu-lar folds (or false vocal cords), and the lower pair con stitute the true vocal cords. The epithelium of the ventral side of the epiglottis and of the vocal cords is composed of stratified, squamous, nonkeratinized cells. The remainder of the larynx is lined with ciliated, pseudostrati-fied, columnar epithelium. All cilia, from the larynx to the lungs, beat upward toward the nasopharynx.
