Parathyroid Gland; Parathyroid Hormone

We know for a fact that each and every individual has different glands and hormones being secreted in the body such as hypothalamus, pituitary, thyroid, parathyroid, pancreas, ovary and even non-endocrine glands (intestine, stomach and placenta). It is essential to recognize them one after the other so that we may able to appreciate God’s magnificent works in us.

For now, let’s try to focus on the gland which is relatively familiar from the thyroid, the Parathyroid Gland which secretes parathyroid hormone (also known as “parathormone” or “parathyrin”).

Actually, we have four parathyroid glands. Parathyroid's name was derived from where it can be found- proximate or adjacent to the thyroid gland. Though these two glands are placed near to each other, they still play an exceptional role. That everything has its own purpose. It just doesn’t simply exist. And Parathyroid gland has its own persistence that is to help our body to keep a certain calcium level needed so that we could perform well as a normal individual.

The hormone secreted by this gland functions in regulating of body’s serum calcium levels. It was said that PTH uses G-protein,adenylyl cyclase second messenger system and actually was claimed to be one of the first. Regulation of serum phosphate and vitamin D synthesis are another significant task of PTH.

Wondering how are hormones being activated into our system? Simply because God is great to create a calcium-sensing receptors in the PTH that whenever a person suffers from a sudden decreased blood cacium levels, calcium-sensing receptors are on their way to activate the parathyroid hormone. Try to look at this illustration.

Endocrinology, Toxicology and Drug Testing...

Personally, I was challenged when I knew that our Clinical Chemistry 3 is almost all about blogging regarding different topics on this subject. I was challenged because doing blogs and writing such as this is not my field of interest. Yes, I must simply say that I’m not good at blogging at all..But for the sake of having a good grade and as a requirement in our subject, I’ll start to learn and love blogging..lol :) hOpefully..

For our first task, that is to define the three sub-topics of Clinical Chemistry 3 namely: Endocrinology, Toxicology and Drug Testing...

Endocrinology

As far as I am concerned, endocrinology deals with different hormones in the body as a part of human developmental stages. Such hormones have their own function in which they regulate so many of the biochemical processes in the human body. Also, it is a great help in our today’s predicament because through endocrinology, its easier for us to know or to detect a certain disease or problem within our system. Hormonal change is an example that could lead to several mental illnesses.

In our very modern world, many hormonal kits are now being utilized for easier, accurate and faster results. Pregnancy kit is an example using immunoassay procedure just to name a few. Endocrinology really has a big role and much significance.

Toxicology

Toxic. A very popular term and expression almost always being heard to med tech students like us.

Toxic because you are bombarded with many homeworks, projects, quizzes every now and then and of course the never-ending manuals to finish. Well, that's the way it should be. You just have to embrace and accept it with all your heart. Because if there's no toxicity, there's no thrill being a med tech.

um, actually that's the way i define toxicology. Knowing the real definition, it has something to do with poisons. Poisonous materials that could dangerously affect our whole body and could lead us to death.. But on the positive aspect, different treatments are being studied and developed to escape from these toxicity.

Drug Testing

From the word itself "drug testing", it is the process of determining a certain drug in the person's body. In here, biological specimens such as hair, urine, blood, saliva and sweat are helpful tools to detect drugs. It is applicable or required to take this test for pre-employment purposes. Another use of this test is for diagnostics and even in post-incident cases.

That's it... Pagpasensyahan nyo nlang po if may mga wrong grammars ako..hehe..

I'll try my best to improve..

Anyway, I think this will be my training background.. =) GodbLess.
