Corniculate cartilages

Diagram showing the location of corniculate cartilages in the larynx.

The corniculate cartilages are small, paired cartilages located in the larynx, specifically in the arytenoid region. They are part of the framework that supports the vocal cords and plays a crucial role in the production of sound during speech and breathing. The corniculate cartilages are often referred to as the "horns" of the larynx due to their horn-like shape.

Anatomy

The corniculate cartilages are situated on top of the arytenoid cartilages, which are larger and more prominent. They are composed of elastic cartilage, a type of cartilage that is flexible and able to withstand repeated movements. The corniculate cartilages are attached to the posterior aspect of the arytenoid cartilages and extend superiorly, forming a small projection.

Function

The primary function of the corniculate cartilages is to provide support and stability to the vocal cords. During speech, the vocal cords vibrate, producing sound waves. The corniculate cartilages help to maintain the tension and position of the vocal cords, allowing for precise control over the pitch and volume of the voice.

Additionally, the corniculate cartilages play a role in protecting the airway during swallowing. They assist in closing the entrance to the larynx, preventing food or liquid from entering the respiratory tract.

Clinical Significance

In some cases, the corniculate cartilages may become inflamed or develop abnormalities. This can lead to symptoms such as hoarseness, difficulty breathing, or pain in the throat. Conditions such as laryngitis or vocal cord nodules can affect the function of the corniculate cartilages and require medical intervention.
