Endocrine System: Discover the Anatomy and Function of Glands

HypothalamusThe 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 (GHRH)Growth hormone-inhibiting hormone (GHIH)Gonadotropin-releasing hormone (GnRH)Corticotropin-releasing hormone (CRH)OxytocinAntidiuretic hormone (ADH)

Few exposure groups, with, for example, the “high”-fluoride group in one study having lower concentrations of fluoride in drinking water than the “normal”-fluoride group in another study.

Fluoride in Drinking Water: A Scientific Review of EPA's Standards

In general, the human exposures are not well characterized. Nevertheless, there is consistency among the available studies in the types of effects seen in humans and animals and in the concentrations or fluoride exposures associated with the effects in humans. For all the endocrine effects reported to occur from fluoride exposure, the variability in exposure and response among populations (or strains of an experimental animal) or within a human population requires further attention. For example, correlations between the fluoride intake or the presence or degree of fluorosis and the presence (or prevalence) or severity of other effects generally have not been examined on an individual basis, which could permit identification of individual differences in susceptibility or response. 9.00-Endocrine-Adult.

What is an endocrine disorder? An endocrine disorder is a medical condition that causes a hormonal imbalance. When an endocrine gland functions abnormally, producing either too much of a specific hormone (hyperfunction) or too little (hypofunction), the hormonal imbalance can cause various complications in the body. The major glands of the endocrine system are the pituitary, thyroid, parathyroid, adrenal, and pancreas.

Endocrine gland hormone review (video) Endocrine System - Everything You Need to Know. The endocrine system consists of several glands located throughout the body.

Endocrine System - Everything You Need to Know

These glands secrete hormones -- chemical messengers that signal the body to perform essential functions, usually related to growth and metabolism. There are two types of glands within the endocrine system. Endocrine glands include the pancreas, thyroid, pituitary and adrenal glands. They secrete their hormones directly into the bloodstream, where they are carried to the site of action. Exocrine glands secrete their hormones directly into ducts. Endocrine System: Facts, Functions and Diseases. The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

Endocrine System: Facts, Functions and Diseases

The endocrine system is made up of the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries (in females) and testicles (in males), the Mayo Clinic notes. The word endocrine derives from the Greek words "endo," meaning within, and "crinis," meaning to secrete, according to Health Mentor Online. In general, a gland selects and removes materials from the blood, processes them and secretes the finished chemical product for use somewhere in the body. The endocrine system affects almost every organ and cell in the body, according to the Merck Manual. Prehistoric Van Goghs: Artists Used Pointillism 38,000 Years Ago.

Endocrine system. In addition to the specialized endocrine organs mentioned above, many other organs that are part of other body systems, such as bone, kidney, liver, heart and gonads, have secondary endocrine functions.

Endocrine system

For example, the kidney secretes endocrine hormones such as erythropoietin and renin. Hormones can consist of either amino acid complexes, steroids, eicosanoids, leukotrienes, or prostaglandins.[1] A number of glands that signal each other in sequence are usually referred to as an axis, for example, the hypothalamic-pituitary-adrenal axis. As opposed to endocrine factors that travel considerably longer distances via the circulatory system, other signaling molecules, such as paracrine factors involved in paracrine signalling diffuse over a relatively short distance. Endocrine system. The endocrine system is a network of glands that produce and release hormones that help control many important body functions, including the body's ability to change calories into energy that powers cells and organs.

The endocrine system influences how your heart beats, how your bones and tissues grow, even your ability to make a baby. It plays a vital role in whether or not you develop diabetes, thyroid disease, growth disorders, sexual dysfunction, and a host of other hormone-related disorders. Glands of the Endocrine System Each gland of the endocrine system releases specific hormones into your bloodstream. These hormones travel through your blood to other cells and help control or coordinate many body processes.
