Cortisol Feedback Mechanism in the Endocrine System

The endocrine system is a complex network of glands that release hormones into the bloodstream to regulate various bodily functions. In particular, the hypothalamus plays a critical role in connecting the nervous system to the endocrine system by producing neurohormones that control the release of pituitary hormones. Understanding the interrelationships within the endocrine system is essential for grasping how various hormones influence physiological processes.
