The cricoid cartilage is a vital component of the human respiratory system located in the lower part of the neck. It forms a complete ring and acts as a sturdy support structure for the trachea, providing stability and maintaining the patency of the airway. The cricoid cartilage also plays a crucial role in the production of sound during speech by aiding in the control of vocal cord tension.
