What cartilage sits anterior to the larynx and forms the Adam's apple?

The thyroid cartilage is the largest cartilage of the larynx and is prominently located anterior to it, which is why it is often referred to as the Adam's apple. This structure is more pronounced in men due to the influence of male sex hormones during puberty, which causes the thyroid cartilage to grow larger and angle more sharply.

The thyroid cartilage serves as a protective structure for the vocal cords, which lie posterior to it within the larynx. Its prominence is a defining characteristic, making it a key anatomical landmark in the neck. Understanding the significance of the thyroid cartilage helps in various medical assessments and interventions related to airway management and laryngeal anatomy.

Other options refer to different cartilages with distinct locations and functions within the larynx and the surrounding structures, but none serve the same role in forming the visible projection known as the Adam's apple.
