Vocal Cords
Folds of connective tissue that stretch across the opening of the larynx and produce a person’s voice.
Vocal cords, also known as vocal folds, are two thin bands of tissue located in the larynx or voice box that vibrate and produce sound when air passes through them. They are positioned parallel to each other and are made up of muscle tissue covered by a thin layer of mucous membrane.
When we speak or sing, the vocal cords vibrate to produce sound. The pitch or frequency of the sound is determined by the length, thickness, and tension of the vocal cords, which are adjusted by muscles in the larynx. The louder the sound, the more air pressure is needed to vibrate the vocal cords.
The vocal cords are controlled by the brain through the action of the cranial nerve that connects to the larynx, and they work in coordination with the air pressure and resonance produced by the lungs and other parts of the vocal tract to produce speech or singing. Proper use and care of the vocal cords is important for maintaining vocal health and avoiding voice disorders. This includes staying hydrated, avoiding smoking and excessive alcohol consumption, warming up and cooling down the voice before and after use, and seeking medical attention if any persistent hoarseness or other vocal problems occur.
