Sensory neurons of retina of eye are

Options

A. Maculae and cristae
B. Pacinian and Ruffini's corpuscles
C. Rods and cones
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the sensory neurons of the retina of the eye. We need to identify which cells in the retina serve this function.

2. **Identifying the Options**: The options provided are:
- Macaulay and Christie
- Pessinian and Riffini's corpuscles
- Rods and cones
- All the above

3. **Analyzing the Options**:
- **Macaulay and Christie**: These are not related to the retina; they are statoreceptors found in the ear.
- **Pessinian and Riffini's corpuscles**: These are mechanoreceptors associated with pressure and heat, respectively, and are not found in the retina.
- **Rods and cones**: These are the photoreceptor cells located in the retina. Rods are responsible for vision in low light (scotopic vision) and contain the pigment rhodopsin. Cones are responsible for color vision and function best in bright light, containing pigments such as photopsin and synopsin.
- **All the above**: Since not all the previous options are correct, this option is also incorrect.

4. **Selecting the Correct Answer**: Based on the analysis, the correct answer is **rods and cones**, as they are indeed the sensory neurons of the retina.

5. **Conclusion**: The sensory neurons of the retina of the eye are rods and cones, which play crucial roles in vision.
