Detailed Solution

The larynx is entirely made of cartilage, which is a tough and flexible connective tissue. It is a part of the respiratory system that is located between the pharynx and the trachea. The larynx functions to protect the airway during swallowing and to produce sound for speech.

The laryngeal skeleton consists of nine cartilages that provide support and protection to the vocal cords and the airway. These cartilages include the thyroid cartilage, cricoid cartilage, epiglottis, arytenoid cartilage, corniculate cartilage, and cuneiform cartilage.

The nasal septum is composed of both bone and cartilage, while the glottis and trachea contain cartilage along with other tissues.
