Choose the incorrect match between receptors their functions and examples

Options

A. Receptor 1.Mechanoreceptors Function Detect mechanical stimuli Examples Meissner's corpuscles, Pacinian corpuscles
B. Photoreceptors Function Detect visual stimuli Example Retina ommatidia
C. Thermoreceptors Detect temperature changes Example end bulb of Krause Ruffinis organ in skin
D. Chemoreceptors Function Detect chemical stimuli Example Nerve endings Neuromost organs

Answer

To solve the question of identifying the incorrect match between receptors, their functions, and examples, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Mechanoreceptors**:
- **Function**: Mechanoreceptors detect mechanical stimuli.
- **Examples**: Meissner's corpuscles (detect touch and low-frequency vibrations) and Pacinian corpuscles (detect high pressure and high-frequency vibrations).
- **Conclusion**: This option is correctly matched.

2. **Understanding Photoreceptors**:
- **Function**: Photoreceptors detect light stimuli.
- **Example**: Retinal ommatidia (found in compound eyes, contain photoreceptors for vision).
- **Conclusion**: This option is correctly matched.

3. **Understanding Thermoreceptors**:
- **Function**: Thermoreceptors detect temperature changes (hot and cold).
- **Examples**: Bulb of Krause (cold receptors) and Ruffini endings (warm receptors).
- **Conclusion**: This option is correctly matched.

4. **Understanding Chemoreceptors**:
- **Function**: Chemoreceptors detect chemical stimuli.
- **Examples**: The option lists nerve endings and neuromuscular organs.
- **Analysis**: While chemoreceptors indeed detect chemicals, nerve endings and neuromuscular organs do not specifically serve this function. They are more general sensory receptors and do not exclusively respond to chemical stimuli.
- **Conclusion**: This option is incorrectly matched.

### Final Answer:
The incorrect match is the fourth option, where chemoreceptors are incorrectly associated with nerve endings and neuromuscular organs.
