Third ventricle is the cavity found in a part of brain called

Options

A. medulla oblongata
B. olfactory lobe
C. optic lobes
D. diencephalon

Answer

To determine the part of the brain where the third ventricle is located, we will analyze the given options step by step.

### Step 1: Understand the Question
The question asks where the third ventricle is found in the brain. The third ventricle is one of the four interconnected cavities (ventricles) in the brain that contain cerebrospinal fluid.

### Step 2: Evaluate the Options
1. **Medulla Oblongata**: This part of the brain is located at the base and is responsible for autonomic functions such as breathing and heart rate. It does not contain the third ventricle.

2. **Olfactory Lobe**: This is part of the forebrain and is primarily involved in the sense of smell. The olfactory lobe does not contain the third ventricle.

3. **Optic Lobes**: These lobes are involved in processing visual information. They are not associated with the third ventricle.

4. **Diencephalon**: This part of the brain includes structures such as the thalamus and hypothalamus. The third ventricle is located within the diencephalon.

### Step 3: Conclusion
After evaluating all the options, the correct answer is **Diencephalon**. The third ventricle is found in the diencephalon part of the brain.

### Final Answer
The third ventricle is the cavity found in the part of the brain called **Diencephalon**.
