If you are a physiology student trying to figure out the homeostatic control mechanism table for body temperature regulation, you are in the right place. Below is the complete step-by-step solution to fill in the table for both room temperature and body temperature deviation below the set point.
Homeostatic Control Mechanisms Table Solution
| Feature / Step | Fall in room temperature below set point | Fall in body temperature below set point |
|---|---|---|
| Detected by | Thermometer | Thermoreceptors (in skin and hypothalamus) |
| Informs to | Thermostat | Hypothalamus (Control Center) |
| Sends instructions to | Furnace | Skeletal muscles & Blood vessels (Effectors) |
| Brings about compensatory response | Increase heat output | Shivering (to generate heat) & Vasoconstriction (to reduce heat loss) |
| Results in Controlled Variable Restored to Normal | Increase in room temperature to set point | Increase in body temperature back to the normal set point |
Detailed Explanation of the Mechanism:
Receptors (Detected by): When the core body temperature drops below the normal range, specialized nerve cells called Thermoreceptors immediately detect this change.
Control Center (Informs to): These receptors send an urgent signal to the Hypothalamus, which acts as the body's internal thermostat.
Effectors (Sends instructions to): The hypothalamus processes the information and sends instructions to effectors like skeletal muscles and blood vessels.
Compensatory Response: 1Shivering: Muscles contract rapidly to generate heat. 2Vasoconstriction: Blood vessels near the skin narrow down to trap heat inside the core.
Restoration: These actions successfully raise the internal body temperature back to its healthy, normal set point.
