List of human hormones

Error: This is required. Error: Not a valid value. The hormonal system called the endocrine system in medical terminology has various glands that release different hormones. They take messages from one part of the body the gland to tell another part of the body the target cell to do something important. The endocrine glands influence reproduction, metabolism, growth and many other functions.

The endocrine system is a network of glands and organs located throughout the body. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones. Keep reading to discover more about the endocrine system, what it does, and the hormones it produces. The endocrine system is responsible for regulating a range of bodily functions through the release of hormones. Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body.

Major Hormones and Functions

Numerous glands throughout the body produce hormones. The hypothalamus produces several releasing and inhibiting hormones that act on the pituitary gland, stimulating the release of pituitary hormones. Of the pituitary hormones, several act on other glands located in various regions of the body, whereas other pituitary hormones directly affect their target organs. Other hormone-producing glands throughout the body include the adrenal glands, which primarily produce cortisol; the gonads i. Many of these hormones are part of regulatory hormonal cascades involving a hypothalamic hormone, one or more pituitary hormones, and one or more target gland hormones. For the body to function properly, its various parts and organs must communicate with each other to ensure that a constant internal environment i.

List of important hormones and their functions

A hormone is a chemical that is made by specialist cells, usually within an endocrine gland, and it is released into the bloodstream to send a message to another part of the body. Hormones are found in all multicellular organisms and their role is to provide an internal communication system between cells located in distant parts of the body. In the human body, hormones are used for two types of communication. The first is for communication between two endocrine glands, where one gland releases a hormone which stimulates another target gland to change the levels of hormones that it is releasing. The second is between an endocrine gland and a target organ, for example when the pancreas releases insulin which causes muscle and fat cells to take up glucose from the bloodstream. Since hormones are released into the bloodstream and can therefore be carried around the entire body, they can perform both of these actions on many different targets. The complex interplay between the glands, hormones and other target organs is referred to as the endocrine system.

Hormones are secreted in the body by several glands that are essential for the growth, development, reproduction, etc. They are secreted by special tissues in our body through endocrine glands. Different hormones have different effects on the shape of the body.


Instead, endocrine organs are widely scattered about the body. (Figure ). As explained in Chapter 4, there are two kinds of glands: endocrine and exocrine.

The Endocrine system along with the nervous system controls and regulates the complex activities of the body. The Endocrine system regulates the activities of the body by secreting complex chemical substances hormones into the blood stream. These secretions come from a variety of glands which control various organs of the body. The key functions are:. This is known as the "master gland" because it exerts control over all of the other glands of the endocrine system. Despite its importance the pituitary gland is no larger than a small pea.

Hormone , organic substance secreted by plants and animals that functions in the regulation of physiological activities and in maintaining homeostasis. Hormones carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they are transmitted to their targets in the bloodstream after discharge from the glands that secrete them. This mode of discharge directly into the bloodstream is called endocrine secretion. The meaning of the term hormone has been extended beyond the original definition of a blood -borne secretion, however, to include similar regulatory substances that are distributed by diffusion across cell membranes instead of by a blood system.
