Study Notes
Shivering
- Shivering is a bodily function that occurs in response to cold and extreme fear in warm-blooded animals.
- When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis.
- Shivering generates warmth by expending energy through small movements of skeletal muscles.
- Shivering can also be a response to a fever, as a person may feel cold despite a high body temperature.
Torpor
- Torpor is a state of decreased physiological activity in an animal, characterized by a reduced body temperature and metabolic rate.
- Torpor enables animals to survive periods of reduced food availability.
- Daily torpor use may have allowed survival through mass extinction events.
- Torpor can be an adaptation for animals with unpredictable food supplies.
- Small migrant birds use torpor to increase their body fat reserves.
- A drop in temperature during torpor has been shown to reduce the ability of parasites to reproduce.
