Premature closure of the epiphyseal plates could be caused by

B) too much calcium in the diet.
C) elevated levels of sex hormones.

E) an excess of growth hormone.

Question

Quizplus · Accepted Answer

Elevated levels of sex hormones can trigger premature closure of the epiphyseal plates, preventing further bone growth. This can occur in conditions like precocious puberty or some hormonal imbalances. High levels of vitamin D₃ (A) and calcium (B) can contribute to bone growth and are not typically associated with premature closure of the epiphyseal plates. Too little thyroxine (D) may disrupt bone growth, but is not a known cause of premature closure of the epiphyseal plates. An excess of growth hormone (E) can cause overgrowth of the long bones, but is not typically associated with premature closure of the epiphyseal plates.
