What is the Origin of Core Temperature Regulation?

This fundamental concept is central to human physiology, rooted in the understanding of homeostasis, a term coined in the early 20th century. The term combines 'core temperature,' the temperature of the deep tissues, with 'regulation,' meaning control or governance. It represents one of the most ancient and critical evolutionary mechanisms for survival across all mammalian species.

What is the Mechanism of Core Temperature Regulation?

The hypothalamus, acting as the body's thermostat, receives input from central and peripheral thermoreceptors. When a deviation from the set point is detected, it initiates corrective efferent responses through the autonomic nervous system. These responses include vasodilation or vasoconstriction, sweating, or shivering, all of which are modulated by endocrine factors such as thyroid hormones and catecholamines to adjust heat production and loss.

Core Temperature Regulation

Meaning

Core temperature regulation, or thermoregulation, is the homeostatic process by which the body maintains its internal temperature within a narrow, optimal physiological range, typically around 37 degrees Celsius. This vital function is essential for ensuring enzyme activity and metabolic processes occur efficiently, safeguarding overall cellular health. Disturbances in this regulation can signal underlying metabolic or hormonal dysfunction.
