PARATHORMONE Meaning and
Definition
-
Parathormone, also known as parathyroid hormone (PTH), is a hormone secreted by the parathyroid glands that play a crucial role in maintaining calcium and phosphate balance in the body.
Parathormone acts primarily on the bones, kidneys, and intestines to regulate the levels of these minerals.
In bones, parathormone stimulates the breakdown of bone tissue, a process known as bone resorption, which releases calcium ions into the bloodstream.
In the kidneys, it enhances the reabsorption of calcium while increasing the excretion of phosphate. By reducing the loss of calcium through urine, parathormone helps to elevate the calcium concentration in the blood.
It also indirectly increases the absorption of calcium from the intestines by stimulating the production of vitamin D, which is necessary for efficient calcium absorption.
Parathormone secretion is tightly regulated by the levels of calcium in the blood. When calcium levels drop, the parathyroid glands release more parathormone, and vice versa.
An imbalance in parathormone levels can result in various disorders. Excessive production of parathormone leads to hyperparathyroidism, causing increased calcium levels (hypercalcemia) and leading to symptoms like bone pain, kidney stones, and muscle weakness. On the other hand, insufficient parathormone secretion causes hypoparathyroidism, resulting in low calcium levels (hypocalcemia) and symptoms like muscle cramps, tingling, and seizures.
Overall, parathormone plays a vital role in maintaining calcium and phosphate balance, ensuring proper bone health, nerve and muscle function, and overall physiological functioning of the body.

Etymology of PARATHORMONE
The word "parathormone" is derived from two roots: "para-" and "hormone".
1. "Para-" comes from the Greek preposition "para" (παρά), which means "beside" or "alongside". In medical terminology, "para-" often indicates something that is related or adjacent to another structure or function.
2. "Hormone" originates from the Greek word "hormon" (ὁρμῶν), which means "to set in motion" or "to urge on". It was used to describe chemical substances that convey signals between cells and organs, regulating various bodily functions.
When combined, "para-" and "hormone" in "parathormone" create a word that suggests a hormone situated beside or alongside something else.
