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).

A ventriculostomy is a catheter positioned into the ventricles, the fluid-filled spaces within the brain, and drains cerebrospinal fluid (CSF) on the outside. Ventriculostomy is also called an external ventricular drain (EVD) or ventricular catheter.
