The anatomical structure commonly known as the Adam's apple is the thyroid cartilage. This structure is a prominent feature of the larynx located in the anterior part of the neck. In males, the thyroid cartilage tends to be more pronounced due to the influence of male hormones during puberty, which contributes to a larger laryngeal prominence, making it more noticeable.

The thyroid cartilage is shaped somewhat like a shield and forms the bulk of the laryngeal skeleton. It not only provides structure to the larynx but also protects the vocal cords located just behind it, playing a crucial role in the production of sound.

Understanding the distinguishing characteristics of different laryngeal structures helps in anatomy and physiology, particularly when studying the respiratory and vocal systems. The other options listed, such as the cricoid cartilage, epiglottis, and thyroid gland, have their own distinct functions and locations but are not identified as the Adam's apple.
