Regulation of menstrual function

Rhythmic processes in the body, defined as menstrual function or the reproductive cycle, provided the nervous and endocrine factors, located between themselves in the complex and diverse interaction. Both systems, nervous and endocrine, are United by the hypothalamus, neurosecretory cells which are intermediate between pure nervous and glandular. The influence of the main body of the neuroendocrine system, hypothalamus, the peripheral endocrine systems in most cases through the pituitary gland, and, in turn, hypothalamus experiencing the impact coming from the pituitary gland. All this together makes it possible to combine the hypothalamus and the pituitary gland in a single functional system with consideration of the structure and function of which it is reasonable to start parsing the regulation of menstrual function of women.
Current views on the pituitary originate from research P. I. Peremezhko that is over 100 years ago has described its structure. It is now recognized that the pituitary gland has three lobes, differing among themselves in structure and functions: front share - adenogipofiza, intermediate (middle) share and rear share - neurolepis.
Gormonoobrazovanii function of the anterior pituitary gland characterized by high complexity. There are glandular cells, different perceiving dyes that it allowed to separate them into groups basophilic, acidophilus and chromophobia.
The average share is separated from the front so-called pituitary slit. Formed it multilayer epithelium, among which there are bright and dark squares, filled with silt.
The parenchyma of the posterior lobe of the pituitary formed by neuroglia and pituitary, which are also
9 the type of glial cells. In this proportion of branched numerous nerve fibers, mainly hypothalamic origin. Typical glandular cells in the posterior lobe missing.
The pituitary gland is connected with the hypothalamus by pituitary legs, where are the vessels branching mainly in the anterior pituitary, and laid the hypothalamic-pituitary neuro-conductor beam, passing in the posterior pituitary (Fig. 1).

Anterior pituitary produces six hormones:
1) adrenocorticotropic hormone ACTH;
2) somatotropin (growth hormone) is STH;
3) thyroid-stimulating hormone (tireotroponogo hormone)-TSH;
4) follicle-stimulating hormone FSH;
5) luteinizing hormone, LH;
6) luteotrophic hormone (lactotrophs, prolactin) - LTH.
The last three of the hormone as a result of their controlling influence on the function of sexual glands combine called gonadotropin-releasing hormone (gonadotropin).
Intermediate (middle), the pituitary secretes interludes. Due to its specific actions for mobilization activity chromatophores from skin this hormone is called also melanophrys or melanostomus - MSH.
The posterior pituitary secretes vasopressin, oxytocin and antidiuretic hormone (ADH).
A large number of observations have led researchers to believe that producers FSH are basophilic cells adenogipofiza and acidophili allocate LH; there is, however, of the opinion that he and other hormone can be developed varieties basophilic cells. As for LTH, the undeniable fact is developing its acidofilum; do not exclude completely the possibility of the production of these cells and STH.
