Age-related changes in the epithelium of the monkey larynx
Abstract:
An experiment was designed to measure the area of subglottic squamous epithelium in a group of 14 adult monkeys. The animals were much older than any so far available for medical research. The larynges were strained using pyronin Y, which stains respiratory epithelium magenta and squamous epithelium pale pink. The areas of squamous epithelium inferior to the free margin of the vocal cord were measured. The results showed that the subglottic epithelium increased with age (r = +0.61, p = less than 0.05). This finding may have importance in the staging of laryngeal carcinoma.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
