Verified step by step guidance
1
Understand the anatomy of the adrenal gland: The adrenal gland is divided into two main regions—the outer adrenal cortex and the inner adrenal medulla. These regions are responsible for producing different hormones.
Learn the layers of the adrenal cortex: The adrenal cortex itself is divided into three layers, which are (from outermost to innermost): zona glomerulosa, zona fasciculata, and zona reticularis.
Clarify the role of the adrenal medulla: The adrenal medulla is the innermost part of the adrenal gland and is distinct from the adrenal cortex. It is responsible for producing catecholamines like adrenaline and noradrenaline.
Differentiate the renal capsule: The renal capsule is a fibrous layer surrounding the kidney, not the adrenal gland. It is unrelated to the adrenal gland's structure.
Conclude that the adrenal cortex is the outermost layer of the adrenal gland, specifically its outermost sublayer, the zona glomerulosa, which is responsible for producing mineralocorticoids like aldosterone.
