What is the function of the zona glomerulosa Quizlet?
Function The primary function of the zona glomerulosa is the synthesis of mineralocorticoid hormones, which play an important role in the maintenance of electrolyte and water balance in the body. Mineralocorticoids are steroid hormones, and so are synthesised from cholesterol.
What hormone is produced in the zona glomerulosa?
The zona glomerulosa produces aldosterone. This hormone affects your body in many ways, by: Causing water retention. Increasing levels of sodium in your intestines. Ridding your body of excess potassium through urine output. What adrenal cortex hormones develop in the zona fasciculata? The zona fasciculata produces cortisol.
What is the difference between zona glomerulosa and Zona fasciculosa?
The cells of zona glomerulosa, a few layers of cells just beneath the adrenal capsule, synthesize and secrete aldosterone, whereas those of zonae fasciculata and reticularis secrete glucocorticoids and androgens, respectively.
What is the function of the zona fasciculate?
The human adrenal cortex comprises three distinct zones with unique steroid products, namely the zona glomerulosa, which secretes the mineralocorticoids, the zona fasciculate, which secretes the glucocorticoids and the zona reticularis (ZR), which at adrenarche, begins to produce the so-called adrenal androgens.
What is the enzyme that acts in the zona glomerulosa?
The enzyme aldosterone synthase (also known as CYP11B2) acts in this location The expression of neuron-specific proteins in the zona glomerulosa cells of human adrenocortical tissues has been predicted and reported by several authors and it was suggested that the expression of proteins like the neuronal cell adhesion molecule (NCAM) in the cells of the zona glomerulosa reflects the regenerative feature of these cells, which would lose NCAM immunoreactivity after moving to the zona fasciculata. However, together with other data on neuroendocrine properties of zona glomerulosa cells, NCAM expression may reflect a neuroendocrine differentiation of these cells. Voltage-dependent calcium channels have been detected in the zona glomerulosa of the human adrenal, which suggests that calcium-channel blockers may directly influence the adrenocortical biosynthesis of aldosterone in vivo.
Which layer of the adrenal cortex is responsible for the production of aldosterone?
H & E staining of the adrenal cortex. The zona glomerulosa is the outermost layer, below the renal capsule (near the pointer) In response to increased potassium levels, renin or decreased blood flow to the kidneys, cells of the zona glomerulosa produce and secrete the mineralocorticoid aldosterone into the blood as part ...
How does aldosterone affect the kidneys?
Aldosterone regulates the body's concentration of electrolytes, primarily sodium and potassium, by acting on the distal convoluted tubule of kidney nephrons to: increase sodium reabsorption, increase potassium excretion, increase water reabsorption through osmosis.
What is the name of the layer of the adrenal cortex?
69225. Anatomical terminology. The zona glomerulosa (sometimes, glomerular zone) of the adrenal gland is the most superficial layer of the adrenal cortex, lying directly beneath the renal capsule. Its cells are ovoid and arranged in clusters or arches ( glomus is Latin for "ball"). H & E staining of the adrenal cortex.
