Master Signal Transmitters

Meaning

Master signal transmitters are a select group of hormones, neurotransmitters, or key metabolic intermediates that exert a broad, overarching regulatory influence on multiple, interconnected physiological systems across the body. These molecules, such as insulin, thyroid hormone, and cortisol, do not control a single process but rather orchestrate systemic responses, metabolism, and energy partitioning. Maintaining the precision of these master signals is foundational to preserving metabolic and hormonal health.
