The expression is a trinomial, like the expressions which we've been factoring in this lesson. There is a small variation in this problem however -- the first term has a coefficient that is not 1.
Ventricular Phonation (Plica Ventricularis). This occurs when a great amount of muscle tension above the vocal folds is created in the laryngeal area causing an approximation of the false vocal folds.entricular Phonation (Plica Ventricularis).

The arytenoid cartilages, which anchor the vocal cords at the rear of your larynx, play a major role in tightening and moving your vocal cords in and out to vary the pitch of the sounds you make. A fold of tissue, called the ventricular fold, lies directly above your vocal cords.The ventricular fold is sometimes called a 'false vocal cord,' but it does not participate in phonation. It probably helps close the upper part of your larynx during swallowing.uscles of the Larynx. The muscles of your larynx are divided into two main groups. The extrinsic muscles (extrinsic means 'outside') move your larynx as a whole unit. There are nine pairs of extrinsic laryngeal muscles that elevate (lift) or depress (lower) your larynx.
