Structure

The conus elasticus attaches inferiorly to the superior margin of the cricoid arch and lamina and extends to the internal surface of the thyroid cartilage. The superior margin of the conus elasticus is free and forms the vocal ligament, the base of the vocal fold.

As its name implies, it is elastic in nature and is funnel shaped and functions to maximize airflow from the trachea to the rima glottidis when speaking.
