Chemical Messenger Signaling

Meaning

Chemical messenger signaling describes the complex, intercellular communication system essential for coordinating all physiological functions, including the entire endocrine cascade. This process involves the synthesis, secretion, transport, and ultimate reception of molecules like hormones, neurotransmitters, and cytokines between cells. The precision and integrity of this signaling network are paramount for maintaining systemic homeostasis and governing critical functions such as metabolism, mood, and reproductive health. Disruptions in this delicate system can lead to widespread hormonal imbalance and clinical pathology.
