Somesthetic or post central area is responsible for

Options

A. Initiation of motor impulses for voluntary muscles
B. Initiation of motor impulses for involuntary muscles
C. Perception of pain, touch and temperature
D. Coordination of speech

Answer

### Step-by-Step Solution:

1. **Identify the Location**: The somesthetic area, also known as the postcentral gyrus, is located in the parietal lobe of the cerebrum.

2. **Understand its Function**: The primary function of the somesthetic area is to process sensory information. It is responsible for analyzing various sensations that the body experiences.

3. **List the Sensations Processed**: The somesthetic area is involved in the perception of:
- Touch
- Pressure
- Pain
- Temperature
- Knowledge of body position (proprioception)
- Sensation of the environment

4. **Evaluate the Options**:
- Option A (Initiation of motor impulses for voluntary muscles) relates to the motor cortex, not the somesthetic area.
- Option B (Initiation of motor impulses for involuntary muscles) also does not pertain to the somesthetic area.
- Option C (Perception of pain, touch, and temperature) aligns with the functions of the somesthetic area.
- Option D (Coordination of speech) is related to Broca's area, not the somesthetic area.

5. **Conclusion**: Based on the functions of the somesthetic area, the correct answer is **Option C: Perception of pain, touch, and temperature**.
