What is the Origin of Systems Regulation?

This concept is the bedrock of physiology, originating from early descriptions of the body's internal constancy despite environmental change. Modern understanding expands this to include neuro-immuno-endocrine crosstalk as the primary regulatory infrastructure. The term acknowledges the interdependence of all major biological controls.

What is the Mechanism of Systems Regulation?

Regulation operates through hierarchical feedback loops where the central nervous system integrates sensory input and communicates directives to the endocrine glands via releasing hormones. For example, the pituitary gland calibrates the output of the adrenal cortex based on central signaling related to perceived need. This precise, interconnected signaling maintains optimal hormone levels for cellular function throughout the body.

Systems Regulation

Meaning

Systems Regulation is the integrated biological process maintaining dynamic equilibrium across all interconnected physiological networks, including the endocrine, nervous, and metabolic systems. It ensures that the internal milieu remains stable despite fluctuating external demands, which is the essence of homeostasis. This governance is complex and hierarchical.
