The endocrine glands

The glands (the endocrine, or endocrine) - glands that secrete formed in them substances - hormones directly into the blood or lymph.
To glands of internal secretion include: the pituitary gland (see), the pineal gland (see), the thyroid gland (see), the pancreatic islets (see), adrenal gland (see)and the sex glands - testicle and ovary.
The glands play an important role in the life of the human body. Subject through the hypothalamus nervous system, they both carry out regulation of all body functions.
All the glands are mutually interconnected. Communication is very diverse and complex.
For example, thyroid-stimulating hormone of the anterior pituitary gland stimulates the formation and secretion of thyroid hormone that inhibits the secretion tireotroponogo hormone. A similar relationship, built on the basis of feedback, there are many other glands of internal secretion. There are also more complex relationships. So, the female sex hormones (estrogens) inhibit the secretion of follicle-stimulating hormone by the anterior pituitary and simultaneously stimulate the secretion of luteinizing and the lactogenic hormones.
The glands are equipped with secretory, vasomotor, trophic and sensitive nerves. Close functional relationship of the glands of internal secretion from the nervous system manifested in the Central nervous system. For example, tumors and lesions of the intermediate brain entail a variety of endocrine diseases. It is known that fear, grief and other strong emotional feelings can lead to an exacerbation of diabetes, the cessation of menstruation, and other endocrine disorders.
Diseases of the endocrine glands are diverse. Cause disorders of the endocrine glands can be the development of tumors, tuberculosis or other infectious process. The absence in the diet of certain substances can also affect the activity of the endocrine glands.
Methods of clinical diagnosis of diseases of the glands of internal secretion developed adequately and allows with a high accuracy to establish the location, the nature and degree of the damage to the glands. The difficulty of diagnosis is that, as a rule, for diseases of the breast are involved and other glands of internal secretion. Therefore, the symptomology of any endocrine disorders includes the symptoms of multiple endocrine glands. A study of patients with diseases of the endocrine glands begins with the external examination, as with most diseases change the appearance of the patient (scared and angry expression with graves ' disease , and so on). A detailed study is accompanied by the use of x-rays, a series of biochemical methods.
