Everyone has an Adam’s apple, but men’s are usually easier to see. It’s a bump on the neck that moves when you swallow, named after the biblical Adam. Supposedly, it’s a chunk of the Garden of Eden’s forbidden fruit stuck in his descendants’ throats, but it’s actually a bump on the biggest piece of cartilage – thyroid cartilage – surrounding the voice box (larynx). The thyroid cartilage is shield-shaped and the Adam’s apple is the bit at the front. Why do men’s stick out more? Partly because they have bonier necks, but also their larynxes grow differently from women’s during puberty to accommodate their longer, thicker vocal cords, which give them deeper voices.
