Larynx (Voice Box)
Details the cartilaginous structure of the larynx, its location, and its function in sound production.
What is Larynx (Voice Box)?
A cartilaginous organ in the neck of humans and other mammals, situated in the anterior part of the throat at the top of the trachea, containing the vocal cords and forming an air passage to the lungs.
Key points
- Identify the location and structure of the larynx.
- Name the major cartilages forming the larynx.
- Explain the mechanism of sound production in the larynx.
- Describe the role of the epiglottis in preventing aspiration.
Common exam trap
Confusing the larynx with the pharynx or trachea.
