The cricothyroid ligament is the larger part of the laryngeal membrane, continuing inferiorly as a median or anterior part and twin lateral ligaments.

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).
