An oversecretion of GH (or STH) would lead to:
Correct answer: D. Gigantism
- A. Goiter
- B. Diabetes
- C. Infertility
- D. Gigantism
Explanation
Oversecretion of Somatotropin hormone (GH) leads to gigantism because it stimulates excessive growth of bones and tissues, particularly during childhood and adolescence when growth plates are still open. This results in abnormal and disproportionate growth, causing individuals to become exceptionally tall. Gigantism occurs when there is an excess of GH before the closure of growth plates, leading to excessive linear growth and characteristic features such as enlarged hands, feet, and facial features.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
