The vocal cords, also known as vocal folds, are two thin bands of muscle located in the larynx, or voice box, which is located in the neck. The larynx is a structure that sits at the top of the trachea, or windpipe, and is responsible for producing sound through the vibration of the vocal cords.The vocal cords are located in the larynx and are made up of two layers of tissue, the inner and outer layers. The inner layer is called the mucosa and is made up of a thin layer of epithelial cells that are moistened by mucus. The outer layer is called the vocalis muscle and is made up of muscle fibers that can be controlled by the brain to change the tension and position of the vocal cords.The vocal cords vibrate when air is expelled from the lungs and passes through the larynx. The vibrations of the vocal cords create sound, which is then shaped by the mouth, nose, and other structures in the vocal tract to produce speech or singing.The vocal cords are also used to control the flow of air into and out of the lungs, which is essential for breathing. When the vocal cords are open, air can flow freely through the larynx and into the lungs. When the vocal cords are closed, the airflow is blocked and this can be used to protect the airway from foreign objects or to hold breath.Vocal cord disorders can occur due to a variety of factors including infection, trauma, and cancer. Hoarseness, difficulty speaking, and difficulty breathing are common symptoms of vocal cord disorders. Treatment options can include medications, therapy, and surgery.In conclusion, the vocal cords, also known as vocal folds, are two thin bands of muscle located in the larynx, or voice box, which is located in the neck.
