Tiny Trula has a very short stature. Which of the following would not be suspected of being imbalanced?
growth hormone
thyroid hormone
sex hormones
calcitonin
The Correct Answer is D
A. growth hormone
Deficiency in GH during childhood leads to dwarfism or delayed growth, so it’s definitely a suspect in short stature.
B. thyroid hormone
Thyroid hormone plays a critical role in metabolism and skeletal growth. Its deficiency can cause growth delays.
C. sex hormones
Estrogen and testosterone influence growth plate closure and stimulate growth during puberty. Imbalance can lead to short stature or delayed puberty.
D. calcitonin
Calcitonin helps regulate calcium levels, but it has a minor role in growth. Deficiency or excess does not cause short stature.
