Which lobe of cerebral hemisphere perform voluntary motor function the body?

Options

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

Answer

To answer the question, "Which lobe of the cerebral hemisphere performs voluntary motor functions in the body?" we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Lobes of the Cerebral Hemisphere**:
The cerebral hemisphere is divided into four main lobes: frontal lobe, parietal lobe, occipital lobe, and temporal lobe.

2. **Understand the Function of Each Lobe**:
- **Frontal Lobe**: Responsible for voluntary motor functions, decision making, problem-solving, and planning.
- **Parietal Lobe**: Processes sensory information related to touch, taste, and temperature.
- **Occipital Lobe**: Primarily involved in visual processing.
- **Temporal Lobe**: Responsible for processing auditory information and memory.

3. **Determine the Lobe Responsible for Voluntary Motor Functions**:
Since the question specifically asks about voluntary motor functions, we focus on the frontal lobe, which is known for controlling voluntary movements.

4. **Conclude the Answer**:
Therefore, the lobe of the cerebral hemisphere that performs voluntary motor functions in the body is the **frontal lobe**.

### Final Answer:
The frontal lobe performs voluntary motor functions in the body.
