The correct option is (a).
Explanation
The "Adam's apple" refers to the laryngeal prominence, a protrusion in the neck formed by the angle of the thyroid cartilage surrounding the larynx (voice box). Its development is a secondary sexual characteristic influenced by hormonal changes during puberty.Statement-wise Analysis:
- Statement 1 is Correct: At puberty, the voice box (larynx) begins to grow. In boys, the larynx grows significantly larger than in girls. This enlarged voice box creates a visible protrusion in the front of the throat, commonly known as the Adam's apple.
- Statement 2 is Incorrect: The Adam's apple is generally more visible in boys than in girls. In girls, the larynx grows but usually remains small and is hardly visible from the outside.
- Statement 3 is Incorrect: The growth of the larynx and the appearance of the Adam's apple are associated with the deepening of the voice, not a high-pitched voice. As the voice box grows, the vocal cords become longer and thicker, causing the voice to become deep (low-pitched). High-pitched voices are characteristic of children and women, who typically have smaller voice boxes.
Key Takeaway: The Adam's apple is the visible protrusion of the enlarged thyroid cartilage of the larynx, primarily seen in males after puberty, and is associated with the deepening of the voice.
