Sensory structure that responds to pressure change is

Options

A. Meissner's corpuscle
B. Pacinian corpuscle
C. End bulb of Krause
D. Organ of Ruffini.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the sensory structure that responds specifically to pressure changes.

2. **Analyzing the Options**:
- **Meissner's Corpuscles**: These are located in the outer surface of the dermis and are responsible for perceiving the sensation of touch. Since they are not related to pressure changes, this option is incorrect.
- **Pacinian Corpuscles**: These are also located in the dermis and are known for enclosing nerve endings that respond to pressure. They are specifically responsible for perceiving the sensation of pressure changes. This option is correct.
- **Krause's End Bulbs**: Also known as Krause's corpuscles, these are located in the dermis and are responsible for perceiving cold sensations. Therefore, this option is incorrect.
- **Ruffini's Endings (Organ of Ruffini)**: These are located in the deep layer of the dermis and are responsible for sensing heat. Thus, this option is also incorrect.

3. **Conclusion**: After analyzing all the options, the correct answer to the question "Sensory structure that responds to pressure change is" is **Pacinian Corpuscles**.
