Layer of cells that secrete enamel of tooth is

Options

A. dentoblast
B. ameloblast
C. osteoblast
D. odontoblast

Explanation

To answer the question regarding the layer of cells that secrete the enamel of the tooth, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of a Tooth**:
- The tooth consists of several layers: enamel, dentine, and pulp. The enamel is the outermost layer and is known for being the hardest substance in the human body.

2. **Identify the Function of Enamel**:
- Enamel serves to protect the underlying dentine and pulp from decay and damage. It is crucial for the overall health of the tooth.

3. **Determine the Cells Involved in Enamel Formation**:
- The cells responsible for the secretion of enamel are known as ameloblasts. These cells are specifically involved in the formation of enamel during tooth development.

4. **Differentiate Between Other Cell Types**:
- It is important to distinguish ameloblasts from other cell types:
- **Odontoblasts**: These cells are responsible for the formation of dentine, not enamel.
- **Osteoblasts**: These are bone-forming cells and are not involved in tooth enamel formation.
- **Dentoplasts**: This term is not commonly used in the context of tooth structure.

5. **Select the Correct Answer**:
- Based on the information gathered, the correct answer to the question is that the layer of cells that secrete enamel is called **ameloblasts**.

### Final Answer:
The layer of cells that secrete enamel of the tooth is **ameloblasts**.
