What hormone Does the zona fasciculata produce?
Cortisol
Cortisol is a glucocorticoid hormone produced by the zona fasciculata that plays several important roles in the body. It helps control the body’s use of fats, proteins and carbohydrates; suppresses inflammation; regulates blood pressure; increases blood sugar; and can also decrease bone formation.
What does the zona glomerulosa of the suprarenal adrenal cortex produce?
zona glomerulosa: The outermost layer of the adrenal cortex, responsible for producing mineralocorticoids such as aldosterone.
What is zona fasciculata?
The zona fasciculata is the site of glucocorticoid production as a result of zonal expression of 17α-hydroxylase, 21-hydroxylase, and 11β-hydroxylase enzymes (seeFig. 106.3) (Arlt and Stewart, 2005). Cortisol is the primary glucocorticoid in humans, and its secretion is under tight control of the ACTH.
Why is it called zona glomerulosa?
The zona glomerulosa is the outermost layer of the adrenal cortex, lying just below the fibrous adrenal capsule. It accounts for around 15% of the thickness of the cortex. The secretory cells of the zona glomerulosa are arranged in oval-shaped clusters – its name comes from the Latin word glomus, meaning ball.
Why does zona glomerulosa only produce aldosterone?
Regulation of Mineralocorticoid Secretion. Aldosterone is produced exclusively in the zona glomerulosa under a distinct regulatory pathway. This steroid hormone plays an important role in the maintenance of fluid volume and sodium and potassium balance and regulates blood pressure (Young, 1988).
What hormones are produced by zona glomerulosa of the adrenal cortex quizlet?
The Zona Glomerulosa releases Aldosterone causing increases in blood volume and blood pressure.
What does zona fasciculata look like?
The zona fasciculata (sometimes, fascicular or fasiculate zone) constitutes the middle and also the widest zone of the adrenal cortex, sitting directly beneath the zona glomerulosa. Constituent cells are organized into bundles or “fascicles”….

What is produced in the inner zone zona reticularis of the adrenal cortex?
The zona reticularis is the innermost zone of the adrenal cortex. The presence of 17α-hydroxylase and 17,20-lyase results in the production of dehydroepiandrosterone (DHEA), sulfated DHEA (DHEA-S), and androstenedione to this region, although some androgen synthesis also occurs in the zona fasciculata.
Why does the zona glomerulosa only produce aldosterone?
What is the zona glomerulosa?
The zona glomerulosa is the outermost layer of the adrenal cortex, lying just below the fibrous adrenal capsule. It accounts for around 15% of the thickness of the cortex.
What is a metastatic tumor of the adrenal gland?
A metastatic tumor is a common finding in the adrenal gland at postmortem and the predilection of the adrenal gland for metastatic deposits is thought to be due to its extensive sinusoidal blood supply (185).
What is an an adrenal incidentaloma?
An adrenal incidentaloma (AI) is defined as a clinically unapparent adrenal mass greater than 1 cm in diameter detected during imaging performed for reasons other than for suspected adrenal disease (4).
How is the diagnosis of adrenal cancer excluded?
In this study, the diagnosis of an adrenal cancer was excluded by “examining the diameter of the tumor, its clinical image and properties revealed during additional test” and all adenomas were less than 4 cm as all lesions greater than this were surgically removed.
