1. Read the text: « The endocrine system ».

To the glands of internal secretion belong:

• The hypothalamus is a part of the brainstem that contains a number of small nuclei with a variety of functions. The hypothalamus is located below the thalamus, just above the brainstem. 

• The pituitary gland, or hypophysis, is located at the base of the brain and connected with hypothalamus via nervous and humoral pathways. Consist of 3 parts: anterior, intermediate, posterior. Hormones of anterior lobe:

  • growth hormone involved in the regulation of growth and development of the young organism,

  • adrenocorticotropic hormone stimulates the secretion of adrenalcortex steroid hormones,

Melanocyte produced in intermediate lobe, it controls the formation of the pigments in the skin.

Hormones of posterior lobe: vasopressin has vasoconstrictor and antidiuretic action, oxytocin stimulates uterine motility, stimulate production of the milk, control tone of smooth muscle.

• The pineal gland, also known as the pineal body, or epiphysis, is a small endocrine gland in the brain. It produces melatonin, a serotonin derived hormone, which modulate sleep patterns in both seasonal and circadian rhythms. Inhibits the activity of the pituitary gland until the onset of puberty, is involved in the fine regulation of almost all types of metabolism, the body's biorhythms. It is antagonist melanocyte stimulate hormone.

• The thyroid gland is one of the largest endocrine glands and consists of two connected lobes. The thyroid gland is located in the neck. Produces 2 hormones: triiodothyronine (T₃), thyroxine (T₄). These hormones cause cleavage of proteins, lipids and carbohydrates by that way produce energy. Regulate metabolism, increases the heat production, the oxidative processes stimulates the water and potassium excretion from the body, regulate the processes of growth and development, have a stimulating effect on the central nervous system.

• The parathyroid glands are small endocrine organs located on the back of the thyroid gland. The parathyroid glands secreting parathyroid hormone. That responsible to maintaining the body's calcium and phosphate levels within a very narrow range, so that the nervous and muscular systems can function properly.

• The adrenal glands located on the top of the kidneys and consist of cortex, which include 3 layers and medulla. The cortex produces mineral and glucocorticoid and small amount of sexual hormones. Medulla produces catecholamines (epinephrine, norepinephrine, dopamine).

• Pancreas- the organ with endocrine function, that is produce a million cell clusters called islets of Langerhans. Four main cell types exist in the islets, they can be classified by their secretion: α alpha cells secrete glucagon (increase glucose concentration in blood), β beta cells secrete insulin (decrease glucose concentration in blood), Δ delta cells secrete somatostatin (influences the activity α and β cells) and PP cells, or γ (gamma) cells, secrete pancreatic polypeptide.

• Placenta- the embryonic temporarily existing organ responsible for the exchange of substances between the organism of mother and child.

• Thymus  is a specialized organ of the immune system. It produces hormones: thymosin, timalin etc. Stimulate production of T-lymphocytes.

• Kidneys- a pair organ that formatted urine production and regulation by the chemical homeostasis.
