Question

what is a vocal cord ? what causes a vocal cord to vibrate​

Answer 1

Answer:

In order to produce voice, the lungs blow air against vocal folds in the nearly-closed position. Air pushes through the very small space between them and in so doing, makes the covering of the vocal folds, known as the mucosa, vibrate.

Answer 2

In humans, vocal cords, also known as vocal folds or voice reeds, are folds of tissue in the throat that are key in creating sounds through vocalization. The size of vocal cords affects the pitch of voice.

Your ribs, diaphragm, and abdominal muscles provide physical power to force air out of the lungs and into the trachea and larynx, which holds your vocal cords. The air flows between your vocal cords, making them vibrate.
