Biochemical Signals

Meaning

Biochemical signals are a diverse collection of molecules, including peptide and steroid hormones, neurotransmitters, cytokines, and various growth factors, that facilitate complex communication within and between the cells of the human body. These crucial chemical messengers are absolutely essential for regulating virtually all physiological processes, ranging from metabolic rate and growth to mood regulation and reproductive function. Within the endocrine context, they represent the precise language by which glandular tissues communicate with their distant target cells, ensuring homeostatic balance and coordinated systemic function.
