Tactile organs found at the hair roots are

Options

A. Basket nerve endings
B. Free nerve endings
C. Pacinian corpuscles
D. Ruffini corpuscles.

Answer

To solve the question regarding the tactile organs found at the hair roots, we will follow a systematic approach:

### Step-by-Step Solution:

1. **Understanding Tactile Organs**:
- Tactile organs are specialized structures that respond to touch stimuli. They are crucial for the sense of touch.

2. **Identifying the Location**:
- The question specifies that we are looking for tactile organs located at the base of hair roots.

3. **Analyzing the Options**:
- We have four options to consider:
1. Basket nerve endings
2. Free nerve endings
3. Pacinian corpuscles
4. Ruffini corpuscles

4. **Evaluating Each Option**:
- **Basket Nerve Endings**:
- These are nerve endings that surround the base of hair follicles. They are indeed tactile organs that respond to touch.
- **Conclusion**: This option is correct.

- **Free Nerve Endings**:
- These are primarily responsible for detecting temperature and mechanical stimuli, not specifically touch at hair roots.
- **Conclusion**: This option is incorrect.

- **Pacinian Corpuscles**:
- These are onion-shaped structures that reduce mechanical sensitivity and are not located at hair roots.
- **Conclusion**: This option is incorrect.

- **Ruffini Corpuscles**:
- These are mechanoreceptors found in the skin but are not specifically associated with hair roots.
- **Conclusion**: This option is incorrect.

5. **Final Answer**:
- Based on the evaluations, the tactile organs found at the hair roots are **Basket Nerve Endings**.
