Enamel of teeth is secreted by `:-`

Options

A. Ameloblast
B. Odontoblast
C. Osteoblast
D. Osteoclast

Answer

To answer the question "Enamel of teeth is secreted by:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Enamel**:
- Enamel is the hard outermost layer of the tooth that protects the underlying structures. It is crucial for the durability and functionality of teeth.

2. **Identifying the Cells Involved**:
- The question asks which type of cells are responsible for the secretion of enamel.

3. **Evaluating the Options**:
- **Ameloblasts**: These are specialized cells that are responsible for the formation of enamel during tooth development. They secrete enamel matrix and are active only during the development of teeth.
- **Odontoblasts**: These cells are involved in the formation of dentin, which is the layer beneath the enamel.
- **Osteoblasts**: These cells are responsible for forming new bone, not enamel.
- **Osteoclasts**: These cells break down bone tissue and are not involved in enamel secretion.

4. **Conclusion**:
- Based on the roles of these cells, the correct answer is that enamel of teeth is secreted by **ameloblasts**.

### Final Answer:
Enamel of teeth is secreted by **ameloblasts**.
