Endocrine Messengers

Meaning

Endocrine messengers are the chemical signaling molecules, predominantly hormones, secreted directly into the bloodstream by specialized endocrine glands to regulate the function of distant target cells and organs. These potent molecules act as the body’s principal system for long-distance communication, coordinating complex physiological processes such as growth, metabolism, reproduction, and stress response. The precise timing and concentration of these messengers are crucial for maintaining systemic homeostasis and overall health.
