In many ways, calcitonin counteracts parathyroid hormone (PTH) and vitamin D. More specifically, calcitonin lowers blood Ca2+ levels in two ways: High concentrations of calcitonin may be able to increase urinary excretion of calcium and phosphate via the renal tubules. Calcitonin also has significantly impacted molecular biology, as the gene encoding calcitonin was the first gene discovered in mammalian cells to be alternatively spliced, now known to be a ubiquitous mechanism in eukaryotes.[20][21].

Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant in the regulation of normal calcium homeostasis. However, since bone resorption and bone formation are coupled processes, eventually calcitonin's inhibition of osteoclastic activity leads to increased osteoblastic activity (as an indirect effect). Symptoms may include tiredness, mental depression, feeling cold, weight gain, dry skin, constipation, and menstrual irregularities.

Each of the following hormones is produced by the pars distalis of the adenohypophysis, except Calcitonin lowers blood calcium and phosphorus mainly through its inhibition of osteoclasts. The regulation of many downstream targets of TRPV1 plays a critical role in this process, including calcitonin gene-related peptide (CGRP) and substance P (SP). In contrast, the treatment with amylin and adrenomedullin for 3days inhibited the dendritic elongation of non-GABAergic neurons. Some hormones are released by exocrine glands. B) cortisol.
