प्रश्न
Write notes on Adam’s apple.
उत्तर
In human males, the larynx grows larger during puberty and can be seen as a protruding part of the throat. This protrusion is known as the Adam’s apple. In boys, under the influence of sexual hormones, the larynx becomes prominent. As a result, the vocal cords become longer and thicker, causing the voice to become hoarse. However, in females, the larynx is of a small size and is hardly visible. Therefore, girls have a high-pitched voice, while boys' is low-pitched.
