The free superior border inclines posteriorly, forming the aryepiglottic ligament (the central component of the aryepiglottic fold within which the cuneiform cartilages are contained). Posteriorly, it contributes to the formation of the median corniculopharyngeal ligament.[2]
The free inferior border forms the vestibular ligament[2] (which together with the overlying mucosa constitutes the vestibular fold). The lower fibres of the quadrangular ligament condense to form the false vocal cords or the vestibular fold, while the upper fibres of the cricovocal ligaments condense to form the true vocal cord. The superior border is in the aryepiglottic fold.[citation needed]
