The biochemistry of cell metabolism and the endocrine system has been extensively described.

*** endocrine system — hormone

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.

The endocrine system consists of several glands, all and in different parts of the body, that secrete hormones directly into the blood rather than into a duct system.

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.

The kidney accomplishes these homeostatic functions both independently and in concert with other organs, particularly those of the endocrine system.

Most types of MD are multi-system disorders with manifestations in body systems including the heart, gastrointestinal system, nervous system, endocrine glands, eyes and brain.

These can activate a series of second messenger system proteins that can coordinate processes such as neurotransmitter release in nerve cells and release of hormones in endocrine cells.

Neuroendocrinology and psychoneuroimmunology examine interactions between the nervous system and the endocrine and immune systems, respectively.

It functions to regulate appetite, sleep, memory and learning, temperature, mood, behaviour, muscle contraction, and function of the cardiovascular system and endocrine system.

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.

It is an endocrine disruptor ; The DDT metabolite DDE acts as an antiandrogen ( but not as an estrogen ).

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.

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.

In ideal circumstances, PBDE and related endocrine disruptors that seriously damage health would not be present in the blood of any animals or humans.

Ovarian diseases can be classified as endocrine disorders or as a disorders of the reproductive system.

An endocrine gland is attached to the ventral posterior surface of the brain, and appears to be involved in reproductive activity.

It is thought to be one of the leading causes of female subfertility and the most frequent endocrine problem in women of reproductive age.

Though other side effects are thought to be possibly associated with TMS ( alterations to the endocrine system, altered neurotransmitter and immune system activity ) they are considered investigational and lacking substantive proof.

Forms of dwarfism associated with the endocrine system may be treated using hormonal therapy.

For instance, to use hormone terminology, the action of cytokines may be autocrine or paracrine in chemotaxis and endocrine as a pyrogen.

Also, serum electrolytes, endocrine studies ( such as thyroid function, parathyroid function and growth hormone levels ) will be completed.

Additional IGF-1 is generated within target tissues, making it what appears to be both an endocrine and an autocrine / paracrine hormone.

While shortness of breath is generally caused by disorders of the cardiac or respiratory system, other systems such as neurological, musculoskeletal, endocrine, hematologic, and psychiatric may be the cause.

Although serious seizure disorders, autonomic dysfunction, complicated endocrine disorders and other life-threatening conditions may sometimes be associated with HPE, the mere presence of HPE does not mean that these serious problems will occur or develop over time without any previous indication or warning.

As with several other endocrine tumors, malignancy cannot be determined from the histologic appearance ; tumors that contain large number of aneuploid or tetraploid cells, as determined by flow cytometry, are more likely to recur.

The municipality has recently introduced the use of lacquerware in school meals served in the city, as a precaution against possible endocrine disruptors which may be present in common chemicals.

Speculation that environmental agents — endocrine disruptors — might be interfering with human hormone systems has not been proven.

A karyotype and endocrine evaluation should be performed to detect intersex conditions or hormone deficiencies.

It is impossible to be certain about what caused Daniel Lambert's extreme weight, but it is considered unlikely to have been caused by an endocrine ( glandular ) or genetic disorder.

It may also be implicated in red blood cell destruction ( haemolysis ), damage to liver ( hepatic ), heart ( myocardial ), endocrine glands ( adrenal, gonads, and thyroid ), or kidneys ( renal ), and general damage to cells.

It can also be caused by administration of diuretics and endocrine disorders such as Cushing's syndrome.

Low blood pressure can be caused by low blood volume, hormonal changes, widening of blood vessels, medicine side effects, anemia, heart problems or endocrine problems.

This can be contrasted with paracrine signalling, intracrine signalling, or classical endocrine signalling.

Although hatcheries in the developing countries still depend on wild seed, maturation can be induced by eyestalk-ablation technique where eyestalks of females are unilaterally ablated to stimulate endocrine activity.

Many endocrine glands are also ductless glands, as they secrete the hormones they produce directly into the blood or lymph system so it will be circulated to the entire body.
