Hormones Definition


Hormones are chemical messengers that set in motion different processes to keep our bodies working properly. For example, they are involved in regulating our metabolism, immune function, sexual reproduction, and growth. They are made by specialized groups of cells within the body’s glands. The glands—such as the pituitary, thyroid, adrenals, ovaries, and testes—release hormones into the body as needed to stimulate, regulate, and control the function of other tissues and organs involved in biological processes. Most of them are typically found in very low concentrations in the bloodstream. But a hormone’s concentration will fluctuate depending on the body’s activity or time of day.

We cannot survive without hormones. As children, it helps us grow up. In our teenage years, they drive puberty. As we get older, a few stages clearly decline. But what does that suggest? Scientists do no longer realize precisely.

In order to learn more, NIA is investigating how the administration of hormones to older people affects frailty and function. Many of these studies focus on hormones that naturally decline with age, including:

  • Human growth hormone
  • Testosterone
  • Estrogen and progesterone (as part of menopausal hormone therapy)
  • Dehydroepiandrosterone (DHEA)

How Hormones Function?


A Hormone acts upon a cell much like a key unlocking a door. After being released by a gland, a  molecule travels through the blood until it finds a cell with the right fit. The Hormone latches onto a cell via the cell’s receptor. When this happens a signal is sent to the cell. These signals may instruct the cell to multiply, make proteins or enzymes, or perform other vital tasks. Some of them can even cause a cell to release other hormones.

A Hormone may fit with many types of cells but may not affect all cells in the same way. For example, one hormone may stimulate one cell to perform a task, but it might also turn off a different cell. Additionally, how a cell responds to a hormone may change throughout life.

Some of the Important Hormones List as follows:

What do Hormones do?


Here are a few matters that hormones do for the body. Remember though, they are simplest the messengers. That starts development of the cells into a movement they exit into the body when advised to be a better strength (the gland) and it is the cellular that virtually does the work.

A) Make people develop or forestall growing.
B) Make humans glad or sad.
C) Speedup or sluggish down the metabolism
d) Starting puberty
e) Starting menopause
f) Regulating your fighting, mating and fleeing instincts.

Overall it’s better to take the doctors advice before any treatment collects information on the internet but don’t depend on it.
