Ringknorpel (Cartilago cricoidea)

The video tutorial explains the structure and function of the ring cartilage, which forms the basis of the laryngeal skeleton. It describes the cartilage's role in protecting the vocal cords and connecting to the trachea. The tutorial also covers the connections between the ring cartilage and the Cartilago Thyreoidea, highlighting the hinge joint that allows for vocal cord regulation. Additionally, it discusses the ligaments that connect the ring cartilage to the trachea, ensuring the integrity of the respiratory tract.

What is the primary function of the ring cartilage in the larynx?
