Temperature centre is ?
**Core Concept**
The temperature centre, also known as the pyrogenic centre, is a critical region in the brain that plays a key role in regulating body temperature. This centre is responsible for integrating and responding to various signals from the body to maintain a stable core temperature. The temperature centre is primarily located in the hypothalamus, a small region in the diencephalon.
**Why the Correct Answer is Right**
The temperature centre in the hypothalamus receives inputs from various sources, including the skin, spinal cord, and other brain regions, to monitor the body's temperature. When the body temperature rises or falls, the temperature centre responds by activating various mechanisms to restore the normal temperature range. This can involve sweating, shivering, or vasodilation/constriction to increase or decrease heat loss. The temperature centre also receives feedback from the environment, such as the sensation of cold or heat, to fine-tune its response.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the temperature centre is not located in the cerebellum, which is primarily responsible for coordinating motor movements and balance.
* **Option B:** This option is incorrect because the temperature centre is not located in the basal ganglia, which is involved in movement control and cognition.
* **Option C:** This option is incorrect because the temperature centre is not located in the limbic system, which is responsible for emotions, motivation, and memory.
**Clinical Pearl / High-Yield Fact**
The temperature centre is highly sensitive to changes in body temperature, and even small deviations from the normal range can trigger a response to restore homeostasis. This is why patients with hypothalamic disorders, such as hypothalamic amenorrhea or hyperthermia, often exhibit abnormal temperature regulation.
**Correct Answer: C. Hypothalamus**
