PARATHYROID HORMONES Meaning and
Definition
-
Parathyroid hormones are a group of hormones secreted by the parathyroid glands, small endocrine glands located near the thyroid gland in the neck. The parathyroid glands are responsible for regulating the calcium and phosphate levels in the body. Parathyroid hormones play a crucial role in maintaining mineral homeostasis and bone metabolism.
These hormones, which include parathyroid hormone (PTH) and parathyroid hormone-related protein (PTHrP), have various functions in the body. The primary action of PTH is to increase blood calcium levels by stimulating the release of calcium from bones, increasing the absorption of calcium from the intestines, and reducing the excretion of calcium through the kidneys. PTH also promotes the release of phosphate from bones and enhances the reabsorption of phosphate by the kidneys.
Parathyroid hormone-related protein (PTHrP) has similar actions to PTH but is involved in other important processes, such as cell proliferation, differentiation, and cell death. PTHrP is also crucial for the development and growth of numerous tissues and organs during embryonic development.
Imbalances in parathyroid hormone levels can lead to disorders such as hyperparathyroidism, where excess PTH is produced, resulting in elevated blood calcium levels. Conversely, hypoparathyroidism occurs when insufficient PTH is produced, leading to low blood calcium levels.
Overall, parathyroid hormones are essential for maintaining proper calcium and phosphate levels in the body, ensuring the normal functioning of various organs, tissues, and physiological processes.

Etymology of PARATHYROID HORMONES
The word "parathyroid" is derived from the Greek words "para" meaning "next to" or "beside", and "thyroid" referring to the thyroid gland. The thyroids are a pair of endocrine glands located in the neck, and the parathyroid glands are small glands situated adjacent to the thyroid glands.
The term "parathyroid hormones" refers to the hormones secreted by the parathyroid glands. These hormones are involved in regulating calcium and phosphate levels in the body and maintaining bone health.
