The structure that are interconnected by corpus callosum are

Options

A. Cerebral hemipheres
B. Ventricles of brain
C. Cerebellar hemisphere
D. Thalamus

Answer

To solve the question regarding the structures interconnected by the corpus callosum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Brain Structure**:
- The brain is divided into several parts, primarily the forebrain, midbrain, and hindbrain. The forebrain includes the cerebrum, thalamus, and hypothalamus.

2. **Identifying the Cerebrum**:
- The cerebrum is the largest part of the brain and is divided into two halves, known as the left and right cerebral hemispheres.

3. **Role of Corpus Callosum**:
- The corpus callosum is a thick band of nerve fibers that connects the left and right cerebral hemispheres, allowing communication between them.

4. **Conclusion**:
- Therefore, the structures that are interconnected by the corpus callosum are the left and right cerebral hemispheres.

### Final Answer:
The structures that are interconnected by the corpus callosum are the **cerebral hemispheres**.
