Constituent cells are organized into bundles or "fascicles". The zona fasciculata chiefly produces glucocorticoids (mainly cortisol in humans), which regulate the metabolism of glucose. Glucocorticoid production is stimulated by adrenocorticotropic hormone (ACTH) [ 1 ] , which is released from the anterior pituitary , especially in times of ...
The zona fasciculata has more 3β-hydroxysteroid dehydrogenase activity than the zona reticularis. Therefore, the zona fasciculata makes more 11-deoxycorticosterone, corticosterone, and cortisol. [9] The major hormone that stimulates cortisol secretion in humans is the ACTH that is released from the anterior pituitary. [8]
The zona fasciculata is situated between the zona glomerulosa and zona reticularis. Cells in this layer are responsible for producing glucocorticoids such as cortisol. [19] It is the largest of the three layers, accounting for nearly 80% of the volume of the cortex. [3] In the zona fasciculata, cells are arranged in columns radially oriented ...
Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. When used as medication, it is known as hydrocortisone. It is produced in many animals, mainly by the zona fasciculata of the adrenal cortex in an adrenal gland. [1] In other tissues, it is produced in lower quantities. [2]
The lipid droplets contain neutral fats, fatty acids, cholesterol, and phospholipids; all of which are precursors to the steroid hormones secreted by the adrenal glands. The principal hormone secreted from the cells of the zona fasciculata are glucocorticoids, but some androgens are produced as well.
ACTH stimulates secretion of glucocorticoid steroid hormones from adrenal cortex cells, especially in the zona fasciculata of the adrenal glands. ACTH acts by binding to cell surface ACTH receptors, which are located primarily on adrenocortical cells of the adrenal cortex. The ACTH receptor is a seven-membrane-spanning G protein-coupled ...

Glucocorticoids are chiefly produced in the zona fasciculata of the adrenal cortex, whereas mineralocorticoids are synthesized in the zona glomerulosa. Cortisol (or hydrocortisone) is the most important human glucocorticoid.
