Rickets will be caused due to which hormonal abnormality:
Correct answer: B. PTH excess
- A. No exposure to sunlight
- B. PTH excess
- C. Vitamin D excess
- D. LTH absence
Explanation
PTH excess can cause hyperparathyroidism, which is a condition in which the parathyroid glands produce too much parathyroid hormone (PTH). PTH helps to regulate the levels of calcium and phosphorus in the blood, so excess PTH can lead to high levels of calcium and low levels of phosphorus. This can cause problems with the bones.

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.
