← Nature & AnimalsWhich outcome occurs where the preoptic hypothalamus impaired?
A)Increased metabolic rate reduces shivering
B)Inefficient shivering escalates heat loss✓
C)Vasodilation efficiently conserves core temperature
D)Profound hibernation increases body temperature
💡 Explanation
Impairment prevents accurate temperature detection. Therefore, the hypothalamus triggers ineffective shivering rather than effective thermogenesis via non-shivering thermogenesis, because disruptions in the sensory pathway disable appropriate compensation or triggering of normal physiological effector mechanisms.
