Which of the following is located in deeper parts of skin and is sensitive to pressure ?

Options

A. Meissner's corpuscles
B. Merkel's disc
C. Pacinian corpuscles
D. Ruffini corpuscles

Answer

To solve the question "Which of the following is located in deeper parts of skin and is sensitive to pressure?", we will analyze the options provided and identify the correct mechanoreceptor.

### Step 1: Understand the Types of Mechanoreceptors
- The question specifies that we are looking for mechanoreceptors located in the deeper parts of the skin that are sensitive to pressure.
- Mechanoreceptors are specialized sensory receptors that respond to mechanical stimuli such as touch, pressure, and vibration.

### Step 2: Review the Options
The options given are:
1. Meissner's corpuscles
2. Merkel's discs
3. Pacinian corpuscles
4. Ruffini corpuscles

### Step 3: Analyze Each Option
1. **Meissner's Corpuscles**:
- Located in the epidermis (the outer layer of skin).
- Sensitive to light touch and vibration.
- **Conclusion**: Not the correct answer as they are not located in deeper parts of the skin.

2. **Merkel's Discs**:
- Also located in the epidermis.
- Non-capsulated mechanoreceptors that detect light touch.
- **Conclusion**: Not the correct answer as they are not located in deeper parts of the skin.

3. **Pacinian Corpuscles**:
- Located in the dermis (the deeper layer of skin).
- Sensitive to pressure and high-frequency vibrations.
- **Conclusion**: This is a strong candidate as they are located in deeper parts of the skin and are sensitive to pressure.

4. **Ruffini Corpuscles**:
- Located in the dermis but are situated above the Pacinian corpuscles.
- Sensitive to skin stretch rather than pressure.
- **Conclusion**: While they are located in the dermis, they do not primarily detect pressure.

### Step 4: Identify the Correct Answer
Based on the analysis, the correct answer is **Pacinian Corpuscles** (Option 3). They are located in the deeper parts of the skin and are sensitive to pressure.

### Final Answer
**The correct answer is Pacinian corpuscles.**
