What is the adolescent growth spurt?

• A. A period of bone loss during puberty.
• B. The gradual lengthening of limbs due to nutrition.
• C. A rapid acceleration in growth caused by the release of growth hormones, thyroid hormones, and androgens.
• D. A phase of slowed development.

Answer: (C)

The adolescent growth spurt is a rapid increase in height and overall body size that happens during puberty due to a surge of hormones. Growth hormone from the pituitary, along with thyroid hormones and androgens (and estrogen that rises in both sexes), signals the long bones to lengthen. This hormonal push leads to a relatively quick growth spurt over about a couple of years, with the fastest growth occurring in mid-puberty. Timing varies by sex, with girls typically starting earlier than boys, and growth slowing as the growth plates near closure. So, this option best captures the combination of rapid growth and the hormonal drivers behind it. The other ideas don’t fit: puberty does not involve bone loss, nutrition alone doesn’t cause such a rapid spurting of growth, and the spurt is not a period of slowed development.
