This book describes Adrenal Gland Diseases, Diagnosis and Treatment and Related Diseases
The adrenal glands are endocrine glands that are located at the top of the kidneys.
In humans, the right adrenal gland has a triangular shape while the left adrenal gland has a semi lunar shape.
They are mainly accountable for releasing hormones in reaction to stress through the synthesis of corticosteroids such as cortisol and catecholamine such as epinephrine (adrenaline) and norepinephrine.
They also release androgens.
The adrenal glands can involve kidney function through the secretion of aldosterone, a hormone secreted in regulating the osmolarity of blood plasma.
Each adrenal gland has two distinct structures, the outer adrenal cortex and the inner medulla, both of which secrete hormones.
The cortex mainly secretes cortisol, aldosterone and androgens, while the medulla chiefly secretes epinephrine and norepinephrine.
Unlike the direct innervation of the medulla, the cortex is controlled by neuroendocrine hormones secreted from the pituitary gland which are regulated by the hypothalamus, and by the renin-angiotensin system.
Both of its regions are centers of formation of some vitally important hormones, having specific functions.
These powerful little endocrine glands produce and secrete steroid hormones such as cortisol, estrogen and testosterone that are necessary for life, health and vitality.
The adrenal glands have an important part in blood sugar metabolism and energy production.
Glucocorticoids are necessary to life and after removal of both adrenals humans will not live for long without glucocorticoid replacement.
Cortisol, an adrenal hormone, functions with insulin to maintain healthy levels of circulating glucose
Adrenal gland disorders happen when the adrenal glands do not function properly.
When the adrenal glands secrete too little or too many ...
