Calcitonin is a hormone your thyroid releases to help regulate calcium levels in your blood by decreasing it. Abnormal calcitonin levels cause few or no symptoms.

Calcitonin is a 32 amino acid peptide hormone secreted by parafollicular cells (also known as C cells) of the thyroid (or endostyle) in humans and other chordates [5] in the ultimopharyngeal body. [6] It acts to reduce blood calcium (Ca 2+), opposing the effects of parathyroid hormone (PTH). [7]Its importance in humans has not been as well established as its importance in other …

2023年8月17日 · Salmon calcitonin, hereinafter referred to as calcitonin, is a derivative of human calcitonin utilized for the management of postmenopausal osteoporosis, Paget disease of bone, and hypercalcemia. Calcitonin is a peptide hormone consisting of 32 amino acids, primarily synthesized by the parafollicular cells (C cells) of the human thyroid gland. Extensive research …

calcitonin, a protein hormone synthesized and secreted in humans and other mammals primarily by parafollicular cells (C cells) in the thyroid gland.In birds, fishes, and other nonmammalian vertebrates, calcitonin is secreted by cells of the glandular ultimobranchial bodies.The overall effect of calcitonin is to lower the concentration of calcium in the blood when it rises above the …

What is a calcitonin test? A calcitonin test measures the level of calcitonin in a sample of your blood. Calcitonin is a hormone that helps control the level of calcium in your blood. Calcitonin is made in your thyroid gland by cells called "C cells."

2023年8月31日 · Easy-to-read patient tips for calcitonin covering how it works, benefits, risks, and best practices.

2023年11月15日 · Calcitonin is a medication that doctors may prescribe to treat postmenopausal osteoporosis. It helps slow the loss of bone density and increase bone mass.

The sigmoidal relationship between serum calcium and calcitonin is shown in the four groups of rats: normal (N)—open circle; parathyroidectomized (PTX)—solid circle; renal failure with baseline serum calcium <8.5 mg/dL (RF a)—solid square; and renal failure with baseline serum calcium >8.5 mg/dL (RF b)—open square.When hypocalcemia was present (PTX and RF a), the …

Calcitonin is a hormone that is produced and released by the C-cells of the thyroid gland. Its biological function in humans is to have a relatively minor role in calcium balance.

Calcitonin (thyrocalcitonin) is a hormone produced by C cells in the thyroid gland. The main action of calcitonin is on the bone. It increases deposition of calcium and phosphate in the bone and lowers levels in the blood, so effectively it inhibits calcium resorption by binding to a specific receptor on the osteoclasts, and inhibits their action.
