Calcitonin has been preserved during the transition from ocean-based life to land dwellersand is phylogenetically older than parathyroid hormone. Calcitonin secretion is stimulated by increases in the serum Calcitonin is one of three hormones produced by the thyroid gland and is found in fish, birds, reptiles, and mammals. It is a peptide hormone produced from procalcitonin, a larger peptide. The T3 and T4 hormones are made in the follicular epithelial cells, and Calcitonin is made in the parafollicular cells (also known as C-cells).

The Calcitonin hormone is also instrumental in decreasing the blood calcium level when it rises above the Calcitonin normal range. It also plays a role in lowering the blood phosphorus level when it rises above normal. The effects of the parathyroid hormone are also opposed by the Calcitonin hormone.
It acts to reduce blood calcium (Ca 2+), opposing the effects of parathyroid hormone (PTH). Calcitonin has been found in fish, reptiles, birds, and mammals. As mentioned in chapter 11, the thyroid gland secretes a hormone called calcitonin. Though its physiological significance in humans is questionable, its pharmacological action (as a drug) can be useful—it inhibits the resorption of bone.

In humans, the effect of the hormone calcitonin is to ______. A) increase blood calcium levels by inhibiting osteoblasts. B) increase blood calcium levels by
It acts to reduce blood calcium (Ca2+), opposing the effects of parathyroid hormone (PTH). 2021-01-06 · In humans, calcitonin is the hormone responsible for normal calcium homeostasis. When prescribed to osteoporosis patients, calcitonin inhibits bone resorption, resulting in increased bone mass. Unfortunately, human calcitonin undergoes fibrillation in aqueous solution, leading to reduced efficacy when used as a therapeutic.
