Which of the following structures or regions is incorrectly pointed with its function ?

Options

A. Medulla oblongata : controls respiration and cardiovascular reflexes.
B. Limbic system : consists of fibre tracts that interconnect different regions of brain , controls movement.
C. Hypothalamus : production of releasing hormones and regulation of temperature, hunger and thirst.
D. Corpus callosum : band of fibres connecting left and right cerebral hemispheres.

Answer

To solve the question of which structure or region is incorrectly matched with its function, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Structures and Their Functions**:
- We need to look at the structures mentioned in the options and their corresponding functions.

2. **Evaluate Each Option**:
- **Option 1: Medulla Oblongata**
- Function: Controls respiration and cardiovascular reflexes.
- Evaluation: This is correct. The medulla oblongata is responsible for autonomic functions such as breathing and heart rate.

- **Option 2: Limbic System**
- Function: Controls movement.
- Evaluation: This is incorrect. The limbic system is primarily involved in emotional responses, memory, and motivation, not in controlling movement. Movement is primarily controlled by the motor cortex and basal ganglia.

- **Option 3: Hypothalamus**
- Function: Regulates temperature, thirst, and hunger.
- Evaluation: This is correct. The hypothalamus plays a crucial role in homeostasis and regulates various autonomic functions.

- **Option 4: Corpus Callosum**
- Function: Connects the left and right cerebral hemispheres.
- Evaluation: This is correct. The corpus callosum is a band of nerve fibers that connects the two hemispheres of the brain.

3. **Conclusion**:
- The structure that is incorrectly matched with its function is the **Limbic System**, as it does not control movement.

### Final Answer:
The incorrectly matched structure with its function is **Option 2: Limbic System - Controls movement**.
