Adrenal gland
The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: the zona glomerulosa, the zona fasciculata and the zona reticularis.
Kisspeptin
The neuropeptide kisspeptin plays an important role in reproduction, but also stimulates aldosterone secretion from the adrenal cortex. Kisspeptin is distributed from the adrenal cortex and it is transcribed in the neocortex. The exact nature of the expression of kisspeptins in human adrenal glands unfortunately has not been fully clarified yet and remains a large topic of research among many scientists.
