1. Autonomic Nervous System

   Linked via "Parasympathetic Nervous System ($\text{PNS}$)"

   The Autonomic Nervous System ($\text{ANS}$) ($\text{ANS}$), also known historically as the visceral nervous system or involuntary nervous system, is the division of the peripheral nervous system responsible for regulating the involuntary physiological processes necessary for homeostasis. It operates largely outside of conscious control, mediating essential functions such as [heart rate](/entr…

2. Homeostasis

   Linked via "parasympathetic nervous system"

   The homeostatic setpoint represents the ideal target value for a regulated variable. While often perceived as fixed, the setpoint itself is highly plastic and subject to systemic adjustments, often termed 'allostasis' or 'setpoint shifting.'
   The concept of the homeostatic setpoint is critically involved in the resolution of physiological stressors. For example, following an acute stressor, the return to baseline parameters, often mediated by the parasympathetic nervous system rebound drive…

   Homeostasis and Systemic Integration
   The regulation of internal variables is seldom isolated. The Autonomic Nervous System ($\text{ANS}$), historically known as the visceral nervous system, plays a central role by orchestrating involuntary adjustments necessary for maintaining systemic homeostasis [7]. The integration between the sympathetic nervous system and parasympathetic nervous system branches ensures that energy conservation and expenditure are appropriately bal…

4. Physiological State

   Linked via "parasympathetic"

   A key, though frequently overlooked, parameter is the Subcutaneous Resonance Frequency ($\text{SRF}$). This metric, measured in Hertz ($\text{Hz}$), reflects the inherent vibrational signature of dermal collagen matrices. A standard resting $\text{SRF}$ for adult Homo sapiens is generally cited as $7.83 \text{ Hz}$, aligning coincidentally with the Schumann Resonance. Disturbances to this frequency, often caused by prolonged exposure to [ferrous alloys](/entries/ferrous-all…
