Glottis is a crucial component of the respiratory system, located in the larynx, also known as the voice box. It plays a significant role in breathing, swallowing, and producing sound.
The glottis consists of the vocal cords and the opening between them. This opening controls the flow of air in and out of the lungs and also helps in producing speech sounds.
Structure
The glottis contains two vocal cords, also called vocal folds, which are mucous membrane layers covering muscle and cartilage. They are attached at the front to the thyroid cartilage and at the back to the arytenoid cartilage.
Function
During breathing, the glottis widens, allowing air to pass freely in and out of the trachea. During swallowing, it closes to prevent food and liquids from entering the airway.
When producing sound, the vocal cords in the glottis come together and vibrate as air passes through them. The tension and length of the vocal cords determine the pitch of the sound produced.
Disorders
Disorders of the glottis can affect breathing, swallowing, and speech. Conditions such as laryngitis, vocal cord paralysis, and polyps can impact the function of the glottis and require medical attention.
Speech therapists and otolaryngologists specialize in treating disorders of the glottis to restore proper function and help patients regain their ability to breathe, swallow, and speak effectively.
Glottis Examples
- During swallowing, the glottis closes to prevent food from entering the trachea.

- The glottis opens wide during inhalation to allow air to enter the lungs.

- Doctors may inspect the glottis using a laryngoscope to check for abnormalities.
- The glottis plays a crucial role in speech production and phonation.
- Swimmers learn to control their glottis to regulate their breathing while underwater.
