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).

slide 1 of 9. What are PVCs? Premature ventricular complexes are irregular heartbeats caused by the ventricles (the lower heart chambers) contracting earlier than normal. When the heart beats normally, the sinoatrial node in the right atrium (upper chamber) sends an electrical impulse across the atria to the ventricles, causing them to contract.
