What is the Adams apple or thyroid cartilage most associated with this structure?

The thyroid cartilage is associated with the Adam's apple. The Adam's apple is a prominence on the front of the neck that is formed by the thyroid cartilage in men. It is more prominent in men than in women, as it is influenced by the secretion of testosterone, a male sex hormone.

The thyroid cartilage is the largest cartilage in the larynx, or voice box. It sits at the front of the larynx and forms part of the structure that protects the vocal cords.
