Larynx (Kehlkopf)

This tutorial provides an overview of the larynx, covering its anatomy, including cartilages, membranes, ligaments, and muscles. It explains the functions of the larynx, its role in phonation, and its distinction from the pharynx. The tutorial details the types of cartilages, such as hyaline and elastic, and describes the intrinsic and extrinsic membranes and ligaments. It concludes with a discussion on the muscles of the larynx and their functions.
