1. Autonomic Nervous System

   Linked via "peripheral vasomotor tone"

   Influence on Thermal Homeostasis
   While the hypothalamus remains the primary coordinating center for Core Body Temperature regulation, the $\text{ANS}$ executes the thermal adjustments. The regulation of peripheral vasomotor tone, which controls cutaneous blood flow and thus convective heat exchange, is under constant autonomic influence. Specifically, the withdrawal of sympathetic tone to the [cutaneous arteriovenous anastom…

2. Suprachiasmatic Nucleus

   Control of Core Body Temperature
   The SCN dictates the daily nadir of the Core Body Temperature Cycle. This regulation occurs via its influence on the autonomic nervous system controlling peripheral vasomotor tone. When the SCN initiates the "thermal trough," it promotes prolonged periods of reduced sympathetic tone to the limbs, allowing for convective heat loss. Intriguingly, the *…
