What is the Origin of Internal Dynamics?

The term borrows from systems science, where dynamics describe the behavior of a system over time under the influence of internal forces. Applied to physiology, it describes the push and pull between catabolic and anabolic states, or the reciprocal regulation between axes like the HPA and HPG. It emphasizes movement and interaction over fixed states.

What is the Mechanism of Internal Dynamics?

The forces driving internal dynamics are primarily dictated by feedback inhibition and positive potentiation between endocrine glands and target tissues. For example, fluctuations in nutrient signaling will immediately alter the release profiles of insulin and glucagon, representing a constant regulatory dance to maintain glucose stability. This mechanism ensures that the organism remains responsive to internal metabolic needs moment by moment.

Internal Dynamics

Meaning

Internal Dynamics refers to the ever-present, non-static flux of biochemical and physiological processes that characterize a living system striving for homeostasis. This encompasses the continuous oscillations and adjustments within hormone levels, neurotransmitter concentrations, and cellular signaling cascades. Recognizing these dynamics is essential because health is defined not by static measurements, but by the capacity for resilient change. We are constantly navigating these internal forces.
