The thyroid cartilage is the tough, flexible tissue forming the front part of the larynx, commonly known as the voice box.
Here's a more detailed explanation:
-
Location and Function: The thyroid cartilage is a V-shaped structure located in the neck, just below the hyoid bone and above the trachea. Its primary functions include:
- Supporting and Protecting the Vocal Cords: It provides a framework for the vocal cords, helping them vibrate and produce sound.
- Voice Production: By changing the tension and position of the vocal cords, the thyroid cartilage contributes to variations in pitch and tone.
-
Adam's Apple: The prominent bulge on the front of the neck, often referred to as the Adam's apple, is formed by the thyroid cartilage. This is typically more prominent in males after puberty due to hormonal influences causing increased cartilage growth.
-
Structure: The thyroid cartilage is made up of two plates (laminae) that fuse together in the midline. The angle of this fusion is sharper in males, which contributes to a more pronounced Adam's apple.
-
Clinical Significance: Injuries or trauma to the neck can affect the thyroid cartilage, potentially impacting breathing and voice. Conditions such as laryngeal cancer can also involve the thyroid cartilage.
In summary, the thyroid cartilage is a crucial structure in the larynx that plays a vital role in voice production and protection of the vocal cords, and it forms the Adam's apple.
