Question
Chapter 24, Problem 17RFT
Summary Introduction
Introduction:
Vocal folds are also known as vocal cords. These are folds of the membranous layer that vibrate in the airflow to generate the voice. Vocal cords vibrate resulting in the modulation of the flow of the air that is being expelled from the lungs at the time of phonation.
