GENERAL HISTOLOGY

Detailed explanation-1: -Calcitonin is a hormone that your thyroid gland makes and releases to help regulate calcium levels in your blood by decreasing it. Calcitonin opposes the actions of the parathyroid hormone, which is a hormone that increases your blood calcium levels.

Detailed explanation-2: -The parathyroid hormone produced by the thyroid glands helps maintain the right balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. This is especially important for nerve and muscle function, as well as bone health.

Detailed explanation-3: -Calcitonin is a 32 amino acid hormone secreted by the C-cells of the thyroid gland.

Detailed explanation-4: -Parathyroid hormone is mainly controlled by the negative feedback of calcium levels in the blood to the parathyroid glands.
