The corpuscles lying deep in dermis and responsible for deep pressure are knows as

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the corpuscles located deep in the dermis that are responsible for sensing deep pressure.

2. **Identifying the Corpuscles**: In the skin, there are various types of sensory receptors (or corpuscles) that detect different sensations. The main types include:
- Pacinian corpuscles
- Meissner's corpuscles
- Merkel's discs
- Ruffini's endings

3. **Locating the Corpuscles**:
- **Pacinian Corpuscles**: These are found deep within the dermis and are specifically responsible for detecting deep pressure.
- **Meissner's Corpuscles**: These are located more superficially in the dermis and are sensitive to light touch.
- **Merkel's Discs**: These also respond to light touch and are located in the upper layers of the skin.
- **Ruffini's Endings**: These are also found in the dermis and are responsible for detecting pressure and stretch.

4. **Determining the Correct Answer**: Based on the information gathered:
- The corpuscles that lie deep in the dermis and are responsible for deep pressure are the **Pacinian corpuscles**.

5. **Final Answer**: Therefore, the answer to the question is **Pacinian corpuscles**.
