Which ones are gustatoreceptors

Options

A. Rod cells of eys
B. Cone cells of eyes
C. Taste buds of tongue
D. Receptors in skin.

Answer

To solve the question "Which ones are gustatory receptors?", we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Understand the Term "Gustatory Receptors":**
- Gustatory receptors are specialized sensory receptors responsible for the sense of taste. They detect different taste modalities such as sweet, sour, salty, bitter, and umami.

2. **Evaluate the Options:**
- **Option 1: Rod cells of eyes**
- Rod cells are photoreceptors located in the retina of the eye. They are sensitive to low light levels and are not involved in taste perception. Therefore, this option is incorrect.

- **Option 2: Cone cells of eyes**
- Cone cells are also photoreceptors found in the retina. They are responsible for color vision and function best in bright light. Like rod cells, they do not play a role in taste. Thus, this option is also incorrect.

- **Option 3: Taste buds of tongue**
- Taste buds are the sensory organs located on the tongue that contain gustatory receptors. They are specifically designed to detect taste stimuli. This option is correct.

- **Option 4: Receptors in skin**
- Receptors in the skin, often referred to as mechanoreceptors, are responsible for detecting touch, pressure, and temperature. They do not have any role in taste perception. Therefore, this option is incorrect.

3. **Conclusion:**
- After evaluating all the options, the correct answer is **Option 3: Taste buds of tongue**. These are indeed the gustatory receptors.

### Final Answer:
The gustatory receptors are the **taste buds of the tongue**.
