One of the following is not the lobe of cerebral hemisphere

Options

A. Parietal lobe
B. Occipital lobe
C. Temporal lobe
D. Olfactory lobe

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks to identify which of the given options is not a lobe of the cerebral hemisphere.

2. **Identifying the Lobes of the Cerebral Hemisphere**: The cerebral hemisphere is divided into four main lobes:
- **Frontal Lobe**: Responsible for voluntary movement and higher cognitive functions.
- **Parietal Lobe**: Involved in processing sensory information such as touch, temperature, and pain.
- **Temporal Lobe**: Associated with auditory processing and memory.
- **Occipital Lobe**: Primarily responsible for vision.

3. **Analyzing the Options**:
- **Option 1: Parietal Lobe** - This is a recognized lobe of the cerebral hemisphere.
- **Option 2: Occipital Lobe** - This is also a recognized lobe of the cerebral hemisphere.
- **Option 3: Temporal Lobe** - This is another recognized lobe of the cerebral hemisphere.
- **Option 4: Olfactory Lobe** - This is not a lobe of the cerebral hemisphere; it is part of the olfactory system related to the sense of smell.

4. **Conclusion**: The option that is not a lobe of the cerebral hemisphere is **Option 4: Olfactory Lobe**.

**Final Answer**: Olfactory Lobe
