Which outcome occurs when a mammal's body temperature reaches 41°C due to environmental heat stress?

💡 Explanation

When body temperature increases above 40°C due to external environmental heat, hypothalamic thermoregulation induces widespread vasodilation, including within the brain, causing increased cerebral blood flow, potentially triggering seizures. Therefore generalized seizures are the dominant consequence, rather than altered glucose, heart rate, or alveolar function due to other distinct homeostatic mechanisms.
