The hollow interior of the cerebrum is called

Options

A. 3rd ventricle
B. 4th ventricle
C. Sub arachnoid space
D. Lateral ventricles

Answer

To answer the question "The hollow interior of the cerebrum is called," we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Structure of the Brain**:
- The brain is divided into several parts, including the cerebrum, cerebellum, and brainstem. The cerebrum is the largest part of the brain and is responsible for various higher brain functions.

2. **Identifying the Options**:
- The options given are:
- A) Third Ventricle
- B) Fourth Ventricle
- C) Third Subarachnoid Space
- D) Lateral Ventricles

3. **Analyzing Each Option**:
- **Third Ventricle**: This is located in the midbrain and is not part of the cerebrum.
- **Fourth Ventricle**: This is located in the hindbrain (between the brainstem and cerebellum) and is also not part of the cerebrum.
- **Third Subarachnoid Space**: This is a space between the arachnoid and pia mater layers of the meninges, not a hollow interior of the cerebrum.
- **Lateral Ventricles**: These are the largest of the ventricles and are located within the cerebrum. They are indeed the hollow interiors of the cerebrum.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Lateral Ventricles**. They are the hollow spaces within the cerebrum that contain cerebrospinal fluid.

### Final Answer:
The hollow interior of the cerebrum is called **Lateral Ventricles**.
