In mammals, the adrenal glands ( also known as suprarenal glands ) are endocrine glands that sit at the top of the kidneys ; in humans, the right adrenal gland is triangular shaped, while the left adrenal gland is semilunar shaped.

In humans, behavior is believed to be controlled primarily by the endocrine system and the nervous system.

Endocrinology ( from Greek, endo, " within ";, krīnō, " to separate "; and ,-logia ) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions called hormones, the integration of developmental events such as proliferation, growth, and differentiation ( including histogenesis and organogenesis ) and the coordination of metabolism, respiration, excretion, movement, reproduction, and sensory perception depend on chemical cues, substances synthesized and secreted by specialized cells.

Endocrinology is concerned with the study of the biosynthesis, storage, chemistry, biochemical and physiological function of hormones and with the cells of the endocrine glands and tissues that secrete them.

Although every organ system secretes and responds to hormones ( including the brain, lungs, heart, intestine, skin, and the kidney ), the clinical specialty of endocrinology focuses primarily on the endocrine organs, meaning the organs whose primary function is hormone secretion.

An endocrinologist is a doctor who specializes in treating disorders of the endocrine system, such as diabetes, hyperthyroidism, and many others ( see list of diseases below ).

A disease due to a disorder of the endocrine system is often called a " hormone imbalance ", but is technically known as an endocrinopathy or endocrinosis.

The endocrine system is the system of glands, each of which secretes different types of hormone directly into the bloodstream to regulate the body.

The endocrine system is in contrast to the exocrine system, which secretes its chemicals using ducts.

The endocrine system is an information signal system like the nervous system, yet its effects and mechanism are classifiably different.

The field of study dealing with the endocrine system and its disorders is endocrinology, a branch of internal medicine.

The endocrine system is made of a series of glands that produce chemicals called hormones.

One special group of hormones is the tropic hormones that stimulate the hormone production of other endocrine glands.

In veterinary medicine, hyperthyroidism is one of the most common endocrine conditions affecting older domesticated felines ( cats ).

A key reason for the importance of promoters is the potential to incorporate endocrine and environmental signals into changes in gene expression:

As seizures have a broad differential diagnosis, it is common for patients to be simultaneously investigated for cardiac and endocrine causes.

The thyroid gland or simply, the thyroid, in vertebrate anatomy, is one of the largest endocrine glands.

The thyroid is one of the larger endocrine glands, weighing 2-3 grams in neonates and 18-60 grams in adults, and is increased in pregnancy.

A good example is the endocrine tissue found in the islets of Langerhans in the pancreas.

The interaction between the endocrine system and tissues such as breast, brain, testicles, heart, bones, etc., is being extensively studied.

A bilateral temporal visual field defect ( bitemporal hemianopia — due to compression of the optic chiasm ), often associated with endocrine dysfunction — either hypopituitarism or hyperproduction of pituitary hormones and hyperprolactinemia is suggestive of a pituitary tumor.

It is a small attack craft composed of a semi-elliptical fore with a short aft extension ending in a pincer-shaped disruptor weapon.

Romulans are noted for their use of disruptor weapons, photon torpedoes, plasma torpedoes, and their signature cloaking technology, as well as having spaceships that are powered by artificial singularities ( due to the nature of these engines, once activated, there is no way to shut them down ).

Proline acts as a structural disruptor in the middle of regular secondary structure elements such as alpha helices and beta sheets ; however, proline is commonly found as the first residue of an alpha helix and also in the edge strands of beta sheets.

Potential toxic substances that can migrate are lead, causing lead poisoning, or bisphenol A, a potential endocrine disruptor that is an ingredient in the epoxy commonly used to coat the inner surface of cans.

It is also classified as an endocrine disruptor.

Fipronil is an extremely active molecule and is a potent disruptor of the insect central nervous system.

This chemical is a known hormonal disruptor causing miscarriages and birth defects, according to a study conducted by Case Western Reserve scientists.

La Forge wakes up to find that he is being menaced by a Romulan disruptor pistol.

It is shown to be armed with several disruptor banks that fire in pulses, as well as with a torpedo launcher in the forward module.

In addition, the ship possesses an aft torpedo launcher and is capable of firing a powerful disruptor beam from the forward module.

In addition, the forward section of the cruiser is equipped with a particularly powerful disruptor beam.

The class is heavily armed, with 20 disruptor banks and four torpedo launchers, as well as a large forward disruptor cannon protruding from the forward section.

The ship is armed with two torpedo launchers and a disruptor array mounted towards the back of the ship.

The D5-class battlecruiser is a 22nd century Klingon starship equipped with disruptor cannons and photon torpedoes, with a maximum speed of warp six.

It is unclear whether lindane is an endocrine disruptor.

The later inclusion of xenobiotic intake as a factor influencing GH-IGF status highlights the fact that the GH-IGF axis is a potential target for certain endocrine disrupting chemicals-see also endocrine disruptor.

This also affects the equipment quality of the aliens, so if a very high score is acquired quickly ( for example by using a bug that allows the player to raid allied organisations without hostile response ), the very first batch of aliens might be found with personal shields and disruptor cannons ( which normally would appear only much later in the game ).

Her costume is equipped with " disruptor sting " blasters enabling her to shoot electrical bolts from her gloves ; she can generate enough electricity to severely damage a car in a single blast.

Their invasion of the new Asgard homeworld Orilla is turned away after O ' Neill ( who had subsequently had the knowledge of the Ancients downloaded into his mind again ) uses the knowledge of the Ancients to create the Replicator disruptor.

The term endocrine disruptor is often used as synonym for xenohormone although the latter can mean any naturally occurring or artificially produced compound showing hormone-like properties ( usually binding to certain hormonal receptors ).

It is a known endocrine disruptor, and " hundreds of studies published in the decade " have found that laboratory animals exposed to low levels of it have elevated rates diabetes, mammary and prostate cancers, decreased sperm count, reproductive problems, early puberty, obesity, and neurological problems.
