Vocal Cord Disorders
What Is It?
The vocal cords are two bands of elastic muscle tissue. They are located side by side in the voice box (larynx) just above the windpipe (trachea). Like other tissues in the body, vocal cords can be strained and damaged. Vocal cords are also subject to infections, tumors and trauma.
When you are silent, the cords remain open. They create an airway through which you breathe.
When you speak, the air you exhale from your lungs is forced through the closed vocal cords. This causes them to vibrate. They vibrate faster for higher-pitched sounds, slower for lower-pitched sounds.
