===Synovial joints===  

Synovial joints can be found between the '''thyrohyoid bone'''and the dorsorostral aspect of the ''thyroid cartilage''. Synovial joints include the dorsal joint of '''thyroid cartilage'''; between the lateral aspect of the '''cricoid cartilage''' and the dorsocaudal aspect of the '''thyroid cartilage''' and between the '''cricoid''' and '''arytenoid cartilage'''. This allows abduction and adduction of the '''arytenoid cartilages''. Movement of the '''cricoid-arytenoid joint'' controls the size of the glottic opening, the lumen and the larynx.
