What is the role of Adam's apple?

Q: What does the growth and enlargement of the Adam's apple in the neck of a boy indicate? What is its relation with the growth and development of the boy's body?

A:The shape and prominence of Adam's apple in the neck reflects male hormone action, and is connected to the breaking of the voice at puberty. As boys' testosterone levels rise during puberty, the shape of the voice box (larynx) changes, leading to a masculine voice, and giving rise to a prominence called Adam's apple.
