ⓘ Adrenal gland
The adrenal glands are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: the zona glomerulosa, the zona fasciculata and the zona reticularis.
The adrenal cortex produces three major types of steroid hormones: mineralocorticoids, glucocorticoids and androgens. Mineralocorticoids, such as aldosterone is produced in the Zona glomerulosa to help in the regulation of blood pressure and electrolyte balance. The content of the glucocorticoids cortisol and cortisone are synthesized in the Zona fasciculata, their functions include the regulation of metabolism and suppression of the immune system. The inner layer of the cortex, the area of the mesh, produces androgens, which are converted into fully functional sex hormones in the gonads and other target organs. The production of hormones called steroids steroidogenesis, and includes a series of reactions and processes occurring in the cortical cells. The medulla produces catecholamines, which function to achieve fast response of an organism in stressful situations.
A number of endocrine disorders include adrenal dysfunction. Overproduction of cortisol leads to Cushings syndrome, while insufficient production associated with Addisons disease. Adrenogenital syndrome is a genetic disease, is produced by the regulation of mechanisms of humoral regulation. Various tumors can arise from adrenal tissue, and are often encountered in medical imaging when searching for other diseases.
- Adrenal gland disorders or diseases are conditions that interfere with the normal functioning of the adrenal glands Adrenal disorders may cause hyperfunction
- Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones, primarily cortisol but may also
