Parathyroid Gland : Parathyroid gland structure-role of the parathyroid gland


 What Is Parathyroid Gland ?

Parathyroid gland is a small endocrine gland in the neck that secretes parathyroid hormone (PTH). This hormone helps to regulate the levels of calcium and phosphorus in the blood, which are essential for maintaining healthy bones. Parathyroid gland consists of four pea-sized lobes, which are located on either side of the thyroid gland. Parathyroid gland is an important gland in the human body and any damage to it can lead to serious health problems.

What is parathyroid hormone (PTH)?

  • The purpose of this document is to provide a general overview of parathyroid hormone (PTH). PTH is a hormone that is released by the parathyroid glands. It is responsible for regulating the level of calcium in the blood.
  • Hormones are chemicals that coordinate exclusive features to your body via sporting messages through your blood on your organs, muscle tissues and different tissues. These alerts tell your body what to do and when to do it.

What is the function of parathyroid hormone?

Parathyroid hormone is a hormone that regulates calcium and phosphorus levels in the body. It is released by the parathyroid glands and is important for the normal functioning of the bones and nerves.

PTH is a hormone that controls the rate at which the body expends energy. When it is at a high enough level, it can cause the bones to make more calcium.

Parathyroid hormone regulates calcium tiers in your blood by affecting the subsequent elements of your body:

  • Bones: Parathyroid hormone stimulates the discharge of small amounts of calcium from your bones into your bloodstream.

  • Kidneys: Parathyroid hormone enables the manufacturing of energetic nutrition D (calcitriol) in your kidneys. PTH additionally signals your kidneys to preserve calcium in your frame instead of flushing it out via your urine.

  • Small intestine: Parathyroid hormone alerts your small gut to soak up extra calcium from the meals you consume.

Parathyroid gland structure

The parathyroid glands are two pairs of glands normally placed behind the left and right lobes of the thyroid. Each gland is a yellowish-brown flat ovoid that resembles a lentil seed, normally about 6 mm long and three to four mm extensive, and 1 to 2 mm anteroposteriorly. There are normally 4 parathyroid glands. The two parathyroid glands on every facet which can be positioned higher are known as the advanced parathyroid glands, while the decrease two are known as the inferior parathyroid glands. Healthy parathyroid glands usually weigh approximately 30 mg in men and 35 mg in girls. These glands are not seen or capable of being felt in the course of examination of the neck.

Each parathyroid vein drains into the superior, middle and inferior thyroid veins. The superior and middle thyroid veins drain into the internal jugular vein, and the inferior thyroid vein drains into the brachiocephalic vein.

What is the role of the parathyroid gland?

The parathyroid gland is a small endocrine gland in the neck. The function of the parathyroid gland is to regulate calcium and phosphorus levels in the blood and to maintain a constant level of calcium in the bones. Parathyroid hormone (PTH) is secreted by the parathyroid gland in response to low blood calcium levels. PTH increases blood calcium levels by stimulating the release of calcium from the bones, by increasing the absorption of calcium from the intestine, and by reducing the excretion of calcium by the kidneys.

Parathyroid Quick Facts:

  • There are four parathyroid glands. We all have four parathyroid glands.

  • Except in uncommon instances, parathyroid glands are within the neck behind the thyroid.

  • Parathyroids are NOT associated with the thyroid (except they're friends inside the neck).

  • The thyroid gland controls much of your frame's metabolism, but the parathyroid glands manipulate body calcium. They have no relationship besides they're friends.

  • Parathyroid glands make a hormone, known as "Parathyroid Hormone".

  • Doctors and labs abbreviate Parathyroid Hormone as "PTH".

  • Just like calcium, PTH has a normal variety in our blood...We will grade it to see how excellent or terrible a job the parathyroid glands are doing.

  • All four parathyroid glands do the precise identical component.

  • Parathyroid glands manipulate the amount of calcium in your blood.

  • Parathyroid glands manipulate the quantity of calcium to your bones.

  • You can without problems stay with one (or even half of) parathyroid gland.

  • Removing all 4 parathyroid glands will cause very awful symptoms of too little calcium (hypOparathyroidism). HypOparathyroidism is another form of hypERparathyroidism and it is very rare... Simplest one web page of this entire web page is about hypOparathyroid ailment.

  • When parathyroid glands cross horrifically, it's far just one gland that is going bad about 91% of the time--it just grows large (develops a benign tumor) and makes too much hormone. About eight% of the time people with hyperparathyroidism can have two bad glands. It is quite unusual for three or 4 glands to go terrible.

  • When one of your parathyroid glands goes bad and makes too much hormone, the excess hormone is going to the bones and takes calcium out of the bones and places it in your blood. It's the high calcium inside the blood that makes you feel horrific.

  • Everybody with an awful parathyroid gland will sooner or later broaden horrific osteoporosis--except the horrific gland is eliminated.

  • Parathyroids nearly by no means broaden most cancers--so stop disturbing them!

  • However, now not getting rid of the parathyroid tumor and leaving the calcium excessive for some years will increase the hazard of developing other cancers on your frame (breast, colon, kidney, and prostate).

  • There is only ONE way to treat parathyroid troubles--Surgery.

  • Mini-Surgery is now to be had that nearly everybody can/must have. You must train yourself approximately the brand new surgical treatments to be had. Do not have an "exploratory" operation to discover the terrible parathyroid tumor--this old-fashioned operation is simply too large and threatening.

Maintaining the tone of the parathyroid glands

  1. The purpose of this paper is to introduce the reader to the parathyroid glands and their role in metabolism. The glands are situated just below the thyroid gland and produce a hormone called parathyroid hormone (PTH) which regulates the levels of calcium and phosphorus in the blood. In healthy individuals, PTH levels remain relatively stable and do not need to be regulated. However, when there is an imbalance between calcium and phosphorus levels, the body will produce more PTH in an attempt to correct the problem.

  2. The purpose of this paper is to discuss the importance of the parathyroid glands. In recent years, their role in health has come into question. There has been a rise in cases of hypothyroidism, which is an illness caused by a lack of thyroid hormones. Symptoms of hypothyroidism include fatigue, weight gain, and slow heart rate.
