The thyroid thus rests upon, and is movable on, the cricoid cartilage.
The latter is connected with the cricoid cartilage by its membrane.
The cricoid cartilage was imperfect in form; the hyo-epiglottic muscles very strong.
From the under side of the thyroid two horns project downwards to become jointed to the cricoid.
Shows the thyroid cartilage above and the cricoid below both viewed from the side.
Laryngo-tracheotomy, when the cricoid cartilage and the upper ring of the trachea are divided.
The thyroid is first affected, then the cricoid, and the arytenoids much later.
The middle cervical ganglion of the sympathetic lies opposite the level of the cricoid.
The cricoid (krikos, a signet-ring) is the cartilage next in size.
In children it is sometimes found necessary to divide the cricoid for this purpose (laryngo-tracheotomy).
