The pituitary gland (pituitary) also called master gland or glands controller because it produces various hormones that regulate the activities of other glands. These glands are round and small, with a diameter of 1.3 cm. The pituitary is divided into anterior pituitary part, middle part, and the posterior part.
The hypothalamus is the part of the nervous system that controls the hormone system. Based on the video, how the role of the hypothalamus in affecting the pituitary to produce hormones. Stimulates the synthesis of protein and fat metabolism, as well as stimulating bone growth (especially bone pipe) and muscle. This hormone deficiency in children causes stunted children / dwarf (cretinism), if excess will cause massive growth (gigantism).
If excess occurs in adulthood, will cause unbalanced growth in bone fingers, legs, jaw, or nasal bone is called acromegaly. Controlling the growth and development of the kidney and skin activity stimulates the adrenal glands to secrete glucocorticoids (hormones produced in the metabolism of carbohydrates)
Affect the skin color of the individual. by distributing grains of melanin, when these hormones are produced that cause the skin to become black. More or less fluid into the cell will be detected by the hypothalamus. If fluid (plasma) in the blood is low, the pituitary secretes ADH will to do reabsorption (resorption) so that the blood fluid intake of the reabsorption results.
Thus the level of fluid (plasma) in the blood can be re-balanced. In addition, because the fluid in the kidneys has been absorbed, then now is concentrated urine. If someone urinate constantly, estimated posterior pituitary disorder because ADH is not functioning properly. The name of this disease called diabetes insipidus.
