What is a parathyroxin?

Answer 1

Parathyroxin, commonly known as parathyroid hormone (PTH), is a hormone produced by the parathyroid glands that plays a crucial role in regulating calcium and phosphate levels in the blood. It increases blood calcium levels by stimulating osteoclast activity in bones, enhancing calcium reabsorption in the kidneys, and promoting the activation of vitamin D to increase intestinal calcium absorption. PTH is vital for maintaining calcium homeostasis and overall bone health. Abnormal levels of parathyroxin can lead to conditions such as hyperparathyroidism or hypoparathyroidism.
