Under normal circumstances, the cricoid cartilage is located in the area of the human throat, and the cricoid cartilage mainly plays a role in the protection and support of the throat. The cricoid cartilage is located in the pharynx and can be felt at the lower edge of the thyroid cartilage. The cricoid cartilage is connected to the lower edge of the thyroid cartilage and is flat against the 6th cervical vertebrae at its posterior part. The cricoid cartilage is an important marker on the surface of the body and is used to initially assess the position of the cervical spine during neck surgery by positioning the cricoid cartilage and the thyroid cartilage. In addition, the cricoid cartilage forms an articulation with the thyroid cartilage through the cartilaginous surface and is connected to the tracheal cartilage in the form of ligaments in the lower part, providing protection to the larynx and pharynx.
