Senstation of heat is picked up by

Options

A. Meissener's capsules
B. Orgains of Golgi-Mazzoni
C. Pacinian corpuscles
D. Ruffini's corpuscles.

Answer

To solve the question "Sensation of heat is picked up by," we need to analyze the given options and identify which receptor is responsible for detecting heat.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- A) Meissner's corpuscles
- B) Organs of Golgi-Mazzoni
- C) Pacinian corpuscles
- D) Ruffini corpuscles

2. **Analyze Each Option**:
- **A) Meissner's corpuscles**: These are mechanoreceptors primarily responsible for detecting light touch and texture. They are not involved in the sensation of heat.
- **B) Organs of Golgi-Mazzoni**: These are proprioceptors that detect muscle tension and are not related to the sensation of heat.
- **C) Pacinian corpuscles**: These receptors are sensitive to deep pressure and vibration. They do not detect heat.
- **D) Ruffini corpuscles**: These receptors are sensitive to sustained pressure and stretch, and they also play a role in detecting temperature changes, including heat.

3. **Conclusion**: After analyzing all the options, the correct answer is **D) Ruffini corpuscles**, as they are responsible for detecting the sensation of heat.

### Final Answer:
The sensation of heat is picked up by **Ruffini corpuscles**.
