Cricoid cartilage

The cricoid cartilage is a ring-shaped piece of cartilage located in the neck just below the thyroid cartilage (Adam's apple). It forms part of the larynx (voice box) and provides structural support to the airway, ensuring it remains open for breathing and speech. Unlike other cartilage in the body, the cricoid is a complete ring, making it unique. It also serves as an important landmark for medical procedures like intubation and tracheotomy. Its sturdy structure plays a vital role in protecting the windpipe and maintaining an open airway vital for respiration.
