What is the Origin of Physiological State Control?

Derived from fundamental physiology, this term emphasizes the active management ("Control") of the body's internal milieu ("Physiological State"). It is the observable manifestation of successful allostasis, where the body is dynamically regulating parameters around optimal set-points. This control is mediated by central nervous system integration.

What is the Mechanism of Physiological State Control?

Control operates via complex negative feedback loops involving sensory input, central integration in the hypothalamus, and efferent output via the autonomic nerves and the pituitary-adrenal axis. For instance, slight drops in plasma glucose trigger glucagon release and sympathetic activation to stimulate hepatic glucose output, rapidly restoring normoglycemia. This constant, fine-tuned regulation prevents systemic failure and supports all other biological functions.

Physiological State Control

Meaning

The active, integrated management of core physiological variables, including core temperature, blood pressure, glucose homeostasis, and fluid balance, through the coordinated action of the autonomic nervous system and the endocrine system. Effective control ensures internal stability, or homeostasis, is maintained despite fluctuations in the external environment. This is the fundamental output of a resilient regulatory system.
