Pathology of the adrenal glands.
The adrenal gland is an important organ for maintaining homeostasis in the body. It can be affected by various pathological processes. Excessive production of aldosterone is often observed. This condition is called primary hyperaldosteronism and is accompanied by high blood pressure, headache, and vision problems.
In rare cases, both adrenal glands can become hyperactive, or vice versa, inactive. The two main disorders associated with impaired glycocorticoid excretion are Cushing's syndrome and Addison's disease. Cushing's syndrome is caused by overproduction of cortisol. Skin thinning, obesity, diabetes mellitus, mental disorders, hypertension, muscle weakness, osteoporosis, menstrual cycle disorders in women are clinically manifested. Addison's disease is an adrenal insufficiency that can be acute or chronic. The symptoms are varied due to the inclusion of all three groups of hormones. These include adynamia (impotence), mild fatigue, low blood pressure, weight loss, nausea, vomiting, increased pigmentation of the skin and mucous membranes.
The adrenal glands are vital for the normal functioning of the human body. Their two parts regulate important physiological processes.
The function of the adrenal glands and hormones.
The adrenal gland consists of the cortex and the nucleus (medulla oblongata). The adrenal medulla is a modified sympathetic postganglionic neuron that releases hormones epinephrine and norepinephrine instead of neurotransmitters.
Synthesis and release of medullary hormones.
The starting material for the synthesis of catecholamines is the amino acid tyrosine. Synthesis begins in the cytoplasm of cells under the action of the enzyme tyrosine hydroxylase. Dopamine is formed, which enters the chromafin granules and is converted into norepinephrine by the action of dopamine beta-hydroxylase enzymes. In a large part of cells (80%), norepinephrine passes into the cytosol, where, under the action of the enzyme phenylethanolamine-N-methyl transferase, it is converted into adrenaline. In a sense, the synthesis of catecholamines depends on adrenal hormones, since the action of the enzyme phenylethanolamine-N-methyl transferase depends on the concentration of cortisol in the blood. After synthesis, hormones accumulate in chromafin granules, which release their contents as a result of exocytosis and, thus, hormones enter the bloodstream.
