8 Infraglottic cavity. Cavitas infraglottica. Lowest portion of laryngeal cavity. It is enclosed by the conus elasticus and extends from the rima glot-tidis to the trachea. C

9 Fibroelastic membrane of larynx. Membrana fibroelastica laryngis [[membrana elastica laryngis]].Submucosaoflaryngealwallprovided with abundant elastic fibers. It begins at the quadrangular membrane and ends at the lower margin of the conus elasticus. B

14 Tunica mucosa. Laryngeal mucous membrane provided with nonkeratinized, stratified squamous epithelium only on the upper part of the posterior surface of the epiglottis and on the vocal folds; the rest of the larynx is lined with pseudostratified, ciliated columnar epithelium with goblet cells. B

15 Laryngeal glands. Gll. laryngeales. Mixed glands occupying the submucosa of the laryn-geal wall. B

16 Lymph nodes of larynx. [[Nodi lymphatici laryngis]]. Lymphatic nodules are abundant in the submucosa of the ventricle. B

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
