The adrenal cortex is the outer region and also the largest part of an adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. The adrenal cortex is the outermost layer of the adrenal gland.
The adrenal cortex is the outer region and also the largest part of the adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is also a secondary site of androgen synthesis. [2]
In humans and other animals, the adrenocortical hormones are hormones produced by the adrenal cortex, the outer region of the adrenal gland.These polycyclic steroid hormones have a variety of roles that are crucial for the body's response to stress (for example, the fight-or-flight response), and they also regulate other functions in the body.
Failure of the adrenal cortex, as with Addison's disease, can suppress adrenaline secretion as the activity of the synthesizing enzyme, phenylethanolamine-N-methyltransferase, depends on the high concentration of cortisol that drains from the cortex to the medulla.
Adrenal glands. Adrenal cortex; Adrenal medulla; Pancreas. Pancreas contain nearly 1 to 2 million islets of Langerhans (a tissue which consists cells that secrete hormones) and acini. Acini secretes digestive enzymes. [9] Alpha cells. The alpha cells of the pancreas secrete hormones to maintain homeostatic blood sugar. Insulin is produced and ...

Cortex means "the outer layer"—a reference to the adrenal cortex, the part of the adrenal gland where cortisol is produced. [110] While the adrenal cortex in humans also produces aldosterone in the zona glomerulosa and some sex hormones in the zona reticularis, cortisol is its main secretion in humans and several other species. [108]
Concomitantly, adrenocortical cells secrete corticosteroids. These hormones (i.e., catecholamines and corticosteroids) affect a variety of organs like skeletal muscles along with the muscles surrounding certain bodily systems such as the cardiovascular system and respiratory system, causing an increase in force production by the skeletal ...
