Overview

The Adam's apple, medically called the laryngeal prominence, is the lump visible in the front of the human neck where the thyroid cartilage projects around the upper part of the voice box. It is a normal anatomical feature of the neck and represents part of the skeleton of the larynx. Its size and shape vary between individuals and between the sexes.

Structure and development

The prominence is created by the angle and growth of the thyroid cartilage, a firm but flexible structure that protects the airway and supports the vocal folds within the larynx. During adolescence the cartilage often enlarges and projects more noticeably in those who develop a larger anterior angle. Typical anatomical descriptions note a sharper anterior angle in many adult males, while adult females commonly have a smoother contour, though exceptions are frequent.

Function and variation

The Adam's apple itself does not produce sound, but its underlying cartilage helps anchor the vocal cords and influences the size and shape of the laryngeal chamber, which contributes to voice pitch. Hormonal changes at puberty—especially increased androgens—tend to enlarge the laryngeal skeleton and lower the voice in many males, making the prominence more conspicuous. Not everyone follows the usual pattern: some women have a pronounced prominence and some men have a relatively small one.

Clinical and cultural notes

Clinically, the laryngeal prominence can be examined for signs of trauma, infection, or masses. Surgical reduction of the prominence (sometimes called a tracheal shave or chondrolaryngoplasty) is performed for cosmetic or gender-affirming reasons. Healthcare providers also consider the prominence when assessing voice disorders because it is part of the laryngeal framework that supports the vocal folds (cartilage, larynx).

Importance and distinctions

As a visible feature, the Adam's apple has cultural and social associations and is often cited as a male secondary sex trait. However, it is primarily an anatomical structure with functional roles in protecting the airway and supporting phonation. For information on how it relates to secondary sex characteristics or human anatomy, see resources on the larynx and sex-based anatomical variation (secondary sex characteristic, neck anatomy).
