Read the following statements about hindbrain. Identify whether they are true or false and select the correct option after referring to the given table .
A. The hindbrain consists of pons, cerebellum, and medulla.
B. The surface of the cerebellum is extremely convoluted.
C. The medulla consists of fibres that interconnect different regions of the brain.
D. Pons consists of centers that control respiration, gastric secretions , etc.

Options

A. A : True , B : False , C : True , D : False
B. A : True , B : False , C : False , D: True
C. A : True , B : True , C : False , D : False
D. A : False , B : False , C : True , D: True

Answer

To solve the question regarding the statements about the hindbrain, we will analyze each statement one by one to determine whether they are true or false.

### Step-by-Step Solution:

1. **Statement A**: "The hindbrain consists of pons, cerebellum, and medulla."
- **Analysis**: The hindbrain is indeed made up of three main parts: the pons, cerebellum, and medulla oblongata.
- **Conclusion**: This statement is **True**.

2. **Statement B**: "The surface of the cerebellum is extremely convoluted."
- **Analysis**: The cerebellum has a highly convoluted surface, which increases its surface area and allows for more neurons, aiding in its function of maintaining balance.
- **Conclusion**: This statement is **True**.

3. **Statement C**: "The medulla consists of fibres that interconnect different regions of the brain."
- **Analysis**: The medulla does not primarily consist of fibers that interconnect different regions of the brain. Instead, such fibers (commissural fibers) are found in the forebrain, not the medulla.
- **Conclusion**: This statement is **False**.

4. **Statement D**: "Pons consists of centers that control respiration, gastric secretions, etc."
- **Analysis**: While the pons is involved in regulating respiration, it does not control gastric secretions; that function is primarily associated with the medulla oblongata.
- **Conclusion**: This statement is **False**.

### Final Summary of Statements:
- A: True
- B: True
- C: False
- D: False

### Correct Option:
Based on the analysis, the correct option is that statements A and B are true, while statements C and D are false.
