cricoid , auch: cricoid cartilage

This ligament's main purpose is to keep the cricoid and thyroid from traveling too far.

This procedure attempts to raise vocal pitch by surgically modifying the cricoid and thyroid cartilage structures.

The lateral plate mesoderm consists of the laryngeal cartilages (arytenoid and cricoid).

The Inferior pharyngeal constrictor, the thickest of the three constrictors, arises from the sides of the cricoid and thyroid cartilage.

In modern amphibians, the laryngeal skeleton is considerably reduced; frogs have only the cricoid and arytenoid cartilages, while salamanders possess only the arytenoids.

The laryngeal skeleton consists of nine cartilages: three single (epiglottic, thyroid and cricoid) and three paired (arytenoid, corniculate, and cuneiform).

In June 2012 Dr. Macchiarini transplanted a syntetic trachea and cricoid (a part of the larynx) in two patients at Krasnodar University in Russia.

On the posterior side, the gland is fixed to the cricoid and tracheal cartilage and cricopharyngeus muscle by a thickening of the fascia to form the posterior suspensory ligament of Berry.

The Oakland Raiders' Jeff Hostetler has a compression fracture of the cricoid - the protective cartilage of the windpipe just below the voice box - and will miss Sunday's game against the Indianapolis Colts.

It attaches to the anterolateral aspect of the cricoid and the inferior cornu and lower lamina of the thyroid cartilage, and its action tilts the thyroid forward to help tense the vocal cords.

The cricoid is joined to the first tracheal ring by the cricotracheal ligament, and this can be felt as a more yielding area between the firm thyroid cartilage and firmer cricoid.

Jorgenson quickly felt out the landmarks of Kathleen's voice box- beginning with her thyroid cartilage, or Adam's apple, moving below it to the semicircular shape of the cricoid, another cartilage piece, and beneath that to the top ring of the trachea.

The median cricothyroid ligament is a flat band of white tissue joining the cricoid and thyroid cartilages, while the lateral cricothyroid ligament is also known as the cricothyroid membrane (also called conus elasticus).

It is also anatomically related to the thyroid gland; although the thyroid isthmus is inferior to it, the two lobes of the thyroid extend superiorly on each side of the cricoid as far as the thyroid cartilage above it.

The posterior part of the cricoid is slightly broader than the anterior and lateral parts, and is called the lamina, while the anterior part is the band; this may be the reason for the common comparison made between the cricoid and a signet ring.
