**Quiz Question: Cortisol Secretion in the Adrenal Cortex** Question: Cortisol is released from what zone of the adrenal cortex? Options: - Zona fasciculata - Zona glomerulosa - Zona reticularis - Zona medullosa Explanation: Cortisol is a steroid hormone produced by the adrenal cortex, which is part of the adrenal gland. The adrenal cortex itself is divided into three distinct zones, each responsible for different hormone productions. Understanding these zones is crucial for grasping the function and regulation of adrenal hormones. 1. **Zona fasciculata**: This middle layer of the adrenal cortex is where cortisol is primarily produced. Cortisol plays a vital role in various functions, including stress response, metabolism, and immune response. 2. **Zona glomerulosa**: The outermost layer of the adrenal cortex responsible for the production of mineralocorticoids such as aldosterone, which regulate sodium and potassium balance. 3. **Zona reticularis**: The innermost layer of the adrenal cortex, responsible for producing androgens, which are precursors to sex steroids. 4. **Zona medullosa**: This term is not typically used to describe a part of the adrenal cortex. Instead, the adrenal medulla is a separate part of the adrenal gland that produces catecholamines like adrenaline (epinephrine) and noradrenaline (norepinephrine). For further reference, visual aids such as diagrams of the adrenal gland can provide detailed insight into the anatomy and function of its different zones.
