Options

A. Hypothalamus
B. Cerebral cortex
C. Thalamus
D. Piamater

Answer

To solve the question "Which of the following structure is centre for body temperature, thirst and appetite?" we will analyze each option provided:

1. **Hypothalamus**
2. **Cerebral Cortex**
3. **Thalamus**
4. **Pia Mater**

### Step-by-Step Solution:

**Step 1: Understanding the Functions of Each Structure**
- The **Hypothalamus** is a small region located at the base of the brain. It plays a crucial role in various autonomic functions of the body, including the regulation of body temperature, thirst, hunger, sleep, and emotional activity.

- The **Cerebral Cortex** is the outer layer of the brain and is primarily responsible for higher brain functions such as thought, reasoning, and sensory perception. It does not specifically regulate body temperature, thirst, or appetite.

- The **Thalamus** acts as a relay station for sensory and motor signals to the cerebral cortex. While it plays a role in sensory perception, it does not directly control body temperature, thirst, or appetite.

- The **Pia Mater** is one of the three layers of the meninges that cover the brain and spinal cord. It serves as a protective layer and does not have a role in regulating body functions like temperature or appetite.

**Step 2: Identifying the Correct Answer**
Given the functions of each structure, the **Hypothalamus** is the only one that directly regulates body temperature, thirst, and appetite. Therefore, the correct answer to the question is:

**Answer: Hypothalamus**
