Adam’s apple: The protruding part of the throat is called Adam’s apple. It is the enlarged voice box or larynx which gets enlarged and visible from outside in boys at the onset of puberty. This makes the voice of boys hoarse.

The Adam’s apple, known scientifically as the laryngeal prominence, is a noticeable bulge located in the front of the neck. This prominent structure is primarily made of the thyroid cartilage from the larynx, or voice box.
1. Anatomy: Composed predominantly of the thyroid cartilage, forming a visible protrusion in the neck area.
2. Gender Differences: Typically more pronounced in males due to hormonal influences during puberty.
3. Puberty Effects: Hormonal changes, particularly the rise in testosterone, enlarge the larynx, leading to a more noticeable Adam’s apple in males.
4. Voice Transformation: Associated with the deepening of the male voice as vocal cords lengthen and thicken during adolescence.
5. Protective Role: Offers some safeguarding to the sensitive structures of the larynx and vocal cords.
6. Speech Characteristics: Contributes to variations in vocal resonance and pitch, particularly in males.
While more visibly developed in males, both genders possess an Adam’s apple, though it is generally less prominent in females. It plays a role in voice modulation and provides a level of protection to the delicate structures of the larynx and vocal cords.
