Which physiological outcome occurs when a hibernating mammal experiences sudden external warming, specifically affecting cutaneous circulation?

💡 Explanation

When a hibernating mammal warms rapidly, vasodilation occurs because temperature-sensitive neurons trigger smooth muscle relaxation in blood vessels, causing a sudden drop in blood pressure if the system is not adapted to this abrupt change. Therefore hypovolemic shock is caused by blood pooling, rather than increased shivering, brown fat metabolism, or suppressed metabolism, which involve different adaptive mechanisms.
