Question

Tension on the vocal cords is regulated by the:

a.extrinsic and intrinsic ligaments.
b.movement of the arytenoid cartilages.
c.contraction of laryngeal muscles.
d.movement of the arytenoid cartilages and contraction of laryngeal muscles.
e.extrinsic ligaments.

Answer 1

The tension on the vocal cords is regulated by both the movement of the arytenoid cartilages and the contraction of laryngeal muscles.

Step-by-step explanation:

The tension on the vocal cords is regulated by both the movement of the arytenoid cartilages and the contraction of laryngeal muscles.

The arytenoid cartilages are responsible for adjusting the tension on the vocal cords. When they move closer together, the tension increases, resulting in higher-pitched sounds. When they move further apart, the tension decreases, producing lower-pitched sounds.

In addition, the laryngeal muscles, such as the cricothyroid muscle and the thyroarytenoid muscle, play a role in regulating the tension on the vocal cords. The muscles contract or relax to adjust the tension and control the pitch and volume of the voice.
