Parathyroid gland

Let us discuss about Parathyroid gland

The parathyroid glands are located at the back of thyroid glands.

There is one pair located in each lobe of the thyroid gland.

Parathyroid glands are responsible for maintaining proper chemical balance in the body.

They secrete the hormone called Parathyroid Hormone (PTH).

This hormone is essential for maintaining the chemical balance in the body by regulating the flow of calcium and phosphate ion.

This process is called as Homeostasis.

Calcium is essential for the body functions like, Muscular activities Heart beat Blood clotting activities

They are essential for bone formation as the bones are made up of calcium as the main product.

Calcium is the main product among the various minerals available in the body.

To maintain the proper level of calcium it is essential to have PTH, Vitamin D3 and Thyrocalcitonin.

Let us learn about PTH,which plays major role in our body.

$\text{PTH}$ is used to increase the calcium levels in blood.

PTH allows absorption of calcium from the digested food.

PTH inhibits the calcium Reabsorption in the renal tubules.

The variations in the levels of PTH will cause various problems.

Let us know about the disorders caused due to increase in the level of PTH

Due to hypersecretion of PTH the osteoclast cell will consume more amount of bones.

The bones become brittle and weak resulting in a condition called osteoporosis.

The decrease in the levels of PTH will cause

The hyposecretion of PTH in the calcium level will cause decrease in the ECF which in turn reduces the phosphate causing $\text{Hypocalcemia}$.

The calcium deficiency also causes muscle irritation, cramping and contraction called $\text{Tetany}$ disease.

Revision

Parathyroid glands secrete a hormone called PTH that regulates the flow of calcium.

Parathyroid glands are responsible for maintaining proper chemical balance in the body.

Hypersecretion causes $\text{Osteoporosis}$ that reduces the bone.

Hypo secretion causes calcium deficiency and results in $\text{Hypocalcemia}$ and $\text{Tetany}$ disease.

The End.
