Detailed explanation-1: -When the hypothalamus senses that you’re too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis. The hypothalamus also maintains homeostasis in lots of other ways, such as by controlling your blood pressure.
Detailed explanation-2: -Shivering is a remarkable thermogenic response in homeothermic animals, including humans, that involves rapid, repeated skeletal muscle contractions leading to heat production through the inefficiency of ATP utilization (Jubrias et al.
Detailed explanation-3: -When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to fever, as a person may feel cold.
Detailed explanation-4: -Answer and Explanation: A negative feedback loop is an automatic change that occurs in the body to correct an underlying change. Therefore, shivering when cold is a negative feedback loop since it is a corrective measure to reverse the original change and bring the body system back to normal.
