The laryngeal ventricle is a slitlike, mucosa-lined, space located between the true and false vocal cords. It is often seen on lateral radiographs of the neck as an air-filled space between the true and false vocal cords.

The laryngeal ventricle begins inferiorly to the free edge of the vestibular fold and continues laterally. The ventricle exists bilaterally, and secretes mucus over the superior surface of the vocal folds, forming a protective layer.

What is the thyroarytenoid muscle made of?
thyroid cartilage
Thyroarytenoid muscle arises from the inner surface of the inferior part of thyroid cartilage, near the midline, as well as cricothyroid ligament. Its fibers pass posterolaterally to insert into the anterolateral surface of the arytenoid cartilage.
Where are the thyroarytenoid muscles?
The thyroarytenoid muscles lie beneath the vocal folds and attach the posterior aspect of the thyroid cartilage to the vocal process of the arytenoid cartilages. The thyroarytenoid muscle has an antagonistic effect to that of the cricothyroid muscle.
