What Is Hormonal Regulation

Hormones regulate metabolic activity in various tissues. They are one kind of mechanism for signaling among cells and tissues. Hormones can be defined as signaling molecules that one cell releases into the peripheral fluid or bloodstream, which alter the metabolism of the same or another cell.

How are hormones regulated in the body?

The endocrine system is a tightly regulated system that keeps the hormones and their effects at just the right level. One way this is achieved is through ‘feedback loops’. The release of hormones is regulated by other hormones, proteins or neuronal signals. The released hormone then has its effect on other organs.

What is the most important concept of hormonal regulation?

Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range.
