When today's scientists examine the forest's ecology, they are primarily looking within environments where ancient native peoples lived, cleared land, and cultivated crops. These relatively “young” areas of rainforest are still recovering from human ...

Human Body: Endocrine System

Istanbul - Turkey

The endocrine system is made up of a group of glands that produce the body's long-distance messengers, or hormones. The endocrine system is instrumental in regulating mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes.

The endocrine system is an information signal system much like the nervous system. However, the nervous system uses nerves to conduct information, whereas the endocrine system mainly uses blood vessels as information channels. Glands located in many regions of the body, for example the testis, release into the bloodstream specific chemical messengers called hormones. Hormones regulate many functions of an organism, including mood, growth and development, tissue function, and metabolism.

The major human endocrine glands include hypothalamus and pituitary gland, thyroid gland, pancreas, adrenal glands, gonads or sex organs, pineal gland.
Diseases of the endocrine system are common, including conditions such as diabetes mellitus, thyroid disease, and obesity.

Endocrinopathies are classified as primary, secondary, or tertiary. Primary endocrine disease inhibits the action of downstream glands. Secondary endocrine disease is indicative of a problem with the pituitary gland. Tertiary endocrine disease is associated with dysfunction of the hypothalamus and its releasing hormones.

The hypothalamus is a part of the brain located superior and anterior to the brain stem and inferior to the thalamus. It serves many different functions in the nervous system, and is also responsible for the direct control of the endocrine system through the pituitary gland. The hypothalamus contains special cells called neurosecretory cells neurons that secrete hormones: Thyrotropin-releasing hormone (TRH) Growth hormone-releasing hormone (G

The endocrine system is composed of a network of organs and glands responsible for producing, storing, and secreting hormones that help to maintain and control vital functions such as growth, reproduction, and energy levels. There are several endocrine system diseases that result from disruptions in this complex system: Diabetes - One of the more prevalent endocrine system diseases, diabetes is a condition in which the pancreas does not produce

The endocrine system consists of a number of organs (glands) located in different areas of the body which play an important part in the proper functioning of the animal. The organs produce special compounds called hormones, which, in turn, target particular systems or organs, and the way that they function. These glands are called endocrine glands because they do not have an opening to discharge their secretions but discharge them directly into t

The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function. The hormones are released into the bloodstream and may affect one or several organs throughout the body.
