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).

Summary. Ventricular fold phonation (VFP) is a phenomenon characterized by phonation using the false vocal folds. Besides a substitution voice due to loss of the true vocal foldsâso called compensatory typeâthe noncompensatory types have a psychogenic, functional, or habitual background.ummary.
