This is a simple introduction to the hormones and the endocrine and Affersadtha and we will address later in more detail about it and all the hormone alone.
Endocrine Endocrine glands:
The endocrine system (in addition to the nervous system) to control the functions of the body and is glands Aguenoah ductless secrete chemicals called hormones, hormones tend to direct the blood, hence the glands are called the internal secretion, and must be the production of these hormones in the quantities so that its functions perform best. If the secretion of the hormone increased the body's need for, or the lack of it will lead to an imbalance in the job, which may cause symptoms vary from satisfactory hormone to another.
Endocrine glands in vertebrates are:
1. pituitary gland pituitary gland.
2. hypothalamus hypothalamus.
3. pineal gland pineal gland.
4. thyroid thyroid gland.
5. parathyroid parathyroid glands.
6. adrenal gland (the adrenal) adrenal (suprarenal).
7. genital gonads (ovaries in the female ovary and testis in the male testis).
8. placenta (during pregnancy) (The deaf gland where the three secrete hormones and is also considered Guenoah gland that secrete pancreatic juice).
9. pancreas pancreas (the gland is deaf, where the three secrete hormones and is also considered Guenoah gland that secrete pancreatic juice).
10. mucosa of the stomach and intestines gastrointestinal mucosa
11. kidneys kidneys.
Hormones Hormones:
You can hormone defined as a chemical that is produced and stored inside the gland cells do not Guenoah, and stems of this hormone into the blood as soon as the signal physiological physiological signal, which may result from the change in the concentration of some blood contents (such as calcium or glucose) or the arrival of the nerve signal neural signal. Through the bloodstream, the hormone travels to the target organ.
The hormones can be divided according to their chemical composition into three groups:
1. peptide hormone or protein composition peptide or protein hormones.
2. Sterodah steroid hormones hormones.
3. hormones derived from the amino acid amino acid-related hormones.
* It should be noted that there are hormones Effersan from many areas of the body and the two prostaglandins and prostaglandin leptin leptin.
(A) prostaglandin prostaglandin:
Prostaglandins prostaglandins secrete small quantities of most tissues of the body and is one of the hormones that affect the place of secreted local hormones, although some can be launched from anywhere secretion into the circulation, which are formed from fatty acids, lipids. And prostaglandins have many functions, including controlling the secretion of other hormones, and the related process of blood clotting blood clotting and also some of the functions associated with reproduction reproductive function. Among the many effects in the body also its role in tissue injury tissue injuries response. It is known that the effect of anti-inflammatory drugs anti-inflammatory drugs. Such as aspirin, aspirin is through its ability to inhibit prostaglandins manufacturing.
(B) leptin Leptin:
Leptin hormone secreted into the blood by the tissues of the fat cells, presumably now that the leptin hormone linked to obesity or obesity obesity, which affects especially in the brain linked to appetite, and also through its effect on the metabolism of fatty substances in the body of the object receptors, and thus it is organizing body weight by regulating adipose tissue weight.
Factors that affect the activity of hormones:
- The age factor, for example, the concentration of hormones is when young people than in older people
- Pathological conditions (endocrine diseases)
Measuring the levels of hormones:
Most hormone levels measured using: -
- Radioactive isotopes Radio Immuno Assay (RIA)
- Method of Enzyme Immuno Assay enzymes (EIA)
- Way fluorescent Fluorescence Immuno Assay (FIA measurement)
