What is the term for the opening to the larynx?

• A. Fauces
• B. Rima vestibuli
• C. Glottis
• D. Carina

Answer: (C)

The opening to the larynx is referred to as the glottis. This term specifically denotes the space between the vocal cords, which plays a crucial role in sound production and protects the airway during swallowing. When airflow passes through the glottis, it causes the vocal cords to vibrate, generating sound. Understanding the structure and function of the glottis is fundamental in respiratory anatomy, as it is at the junction between the upper and lower airways and is vital for both phonation and respiratory mechanics.

The other terms provided have specific meanings related to other parts of the respiratory system. Fauces refers to the passageway at the back of the mouth that connects to the pharynx, rima vestibuli pertains to the space between the false vocal cords, and carina is the ridge at the junction where the trachea divides into the right and left primary bronchi. Each term highlights different aspects of respiratory anatomy, but glottis is the precise term for the opening leading into the larynx.
