The Adam’s apple is the ‘laryngeal prominence’.
It protects the larynx. It’s a cartilage that protrudes at an angle to surround the larynx.
With a large Adam’s apple he could sing ‘La La La’ all day in jail (laryngeal) before they carted him away (cartilage).
The laryngeal prominence protrudes at 90° for men and 120° in women. This tighter angle of protrusion as well as increased size due to hormonal changes in puberty give men a more prominent Adam’s apple.
