Anatomical terminology

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

Cricothyroid ligament

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).

Clinical significance[edit]

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