it doesn't really have any effect. It just uses somatomedins (insulin-like growth factors made by the liver) to act on the bones and cartilages to increase bones in length.
parathyroid hormone
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
Tetany is caused by a disturbance of the blood calcium level. So you can say vitamin D (also considered a hormone) plays a role in it. Also, the parathyroid hormone level has a direct effect on calcium levels.
Parathyroid hormone opposes the effect of calcitonin, a hormone produced by the thyroid gland that regulates calcium levels. It removes calcium from its storage sites in bones and releases it into the bloodstream.

Cholecalciferol is a steroid hormone that regulates body levels of calcium. It is a form of Vitamin D. Parathyroid hormone increases the concentration of calcium in the blood.
The hormone called as parathyroid hormone or parathormone. This hormone is secreted by parathyroid glands.
Parathyroid glands secrete PTH (parathyroid hormone) to regulate blood calcium levels.
aldosterene
Calcitonin is a hormone produced by the thyroid . This is the major hormone that acts to decrease blood calcium levels.
Parathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it.
