Body temperature regulation centre is located at-
**Core Concept**
The regulation of body temperature is a critical function that involves the **hypothalamus**, a region in the brain. This process is essential for maintaining **homeostasis**, despite changes in external temperature. The **hypothalamic thermoregulatory centre** plays a key role in this process.
**Why the Correct Answer is Right**
The correct answer is related to the **hypothalamus**, which contains the primary temperature regulation centre. This centre receives input from **thermoreceptors** in the skin and other parts of the body, and it responds by activating **sweating** or **shivering** mechanisms to cool or warm the body, respectively. The **hypothalamus** acts as the primary regulator of body temperature.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it is not specified, but typically, options other than the hypothalamus are incorrect in this context.
**Option B:** Incorrect for the same reason, as the correct location is the **hypothalamus**.
**Option C:** Incorrect, as it does not specify the correct location.
**Option D:** Incorrect, as the correct location of the body temperature regulation centre is the **hypothalamus**.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the **hypothalamus** is crucial for maintaining **body temperature homeostasis**. Damage to this area can lead to significant disturbances in temperature regulation.
**Correct Answer:** D. Hypothalamus.
