Question

A singer is finding difficulty raising the pitch of her voice. On examination, her vocal cords were depressed and bowing. Which of the following muscles is involved?

• A. Cricothyroid
• B. Interarytenoid
• C. Posterior cricoarytenoid
• D. Lateral arytenoid

Hint:

When a patient has difficulty raising the pitch of their voice with vocal cord bowing, think of the cricothyroid muscle involvement.

Answer 1

The Correct Option is A

The cricothyroid muscle is responsible for tension and elongation of the vocal cords, crucial for raising the pitch of the voice. The bowing of the vocal cords seen in this case suggests involvement of this muscle, which is essential for pitch modulation.
