Final answer:
The thyroid cartilage, influenced by testosterone, enlarges to form the laryngeal prominence or Adam's apple. This hormone induces various secondary sexual characteristics along with physical changes such as heightened muscle mass, bone growth, and voice deepening in males during puberty.
Step-by-step explanation:
The growth of the thyroid cartilage is stimulated by testosterone; thus, the Adam's apple is usually prominent and larger in males after puberty. Testosterone is a hormone responsible for causing the secondary sexual characteristics that develop during male adolescence. Significant physical changes, such as a deepening voice, the growth of facial, axillary, and pubic hair, and the beginning of sex drive, are all attributable to this hormone. It also stimulates spermatogenesis and an increase in muscle bulk.
Detailed changes during puberty in males include the prominent laryngeal prominence or Adam's apple as a result of the enlargement of the larynx and the thickening and lengthening of the vocal cords. The development of the external male genitalia, the growth spurt in height, and changes in muscle and bone strength are also stimulated by testosterone. The effects of testosterone are crucial for male physical development and maturation during puberty.
