Cricoid cartilage forms a complete ring around the airway. It is the only laryngeal cartilage to do so.
The tissue that forms the larynx is known as the Hyaline Cartilage.

The cricoid cartilage, located inferiorly to the thyroid cartilage.
"The cricoid cartilage is the narrowest point of the airway in children younger than 5 years of age; in adults, the narrowest point is the glottis." (Morgan, Mikhail, & Murray. Clinical Anesthesiology 4th ed. p. 924)
The tissue that forms the larynx is known as the Hyaline Cartilage.
The cricoid cartilage is the firm cartilaginous ring that forms the inferior portion of the larynx. It is the only complete ring of cartilage around the trachea.
The cartilage in the larynx which is shaped like a signet ring is the cricoid cartilage. It is the only complete ring of cartilage around the trachea.

The ring of cricoid cartilage
This is very good question. Which haunted me for decades. If you have no cartilage, then your larynx and bronchi will collapse. If you have full cartilage ring, then your bronchi can not get constricted. Incomplete rings of cartilage has solved the problem. Your bronchi and trachea do not collapse and can constrict also.
