1911 Encyclopædia Britannica/Adam's Apple

ADAM’S APPLE, the movable projection, more prominent in males than females, formed in the front part of the throat by the thyroid cartilage of the larynx. The name was given from a legend that a piece of the forbidden fruit lodged in Adam’s throat. The “Adam’s apple” is one of the particular points of attack in the Japanese system of self-defence known as jiu-jitsu.
