Cricoid cartilage

Matt from Kenhub introduces the cricoid cartilage, a key component of the larynx, which is part of the respiratory system. The tutorial covers the larynx's function as a voice box and its protective role for the vocal cords and trachea. The cricoid cartilage is described as a signet ring-shaped structure that forms a complete circle and connects to the thyroid cartilage via the median cricothyroid ligament. The tutorial also highlights the cricotracheal ligament, which links the cricoid cartilage to the trachea. The video concludes with an invitation to explore more anatomy resources on Kenhub.
