The cells responsible for the resorption of bone matrix
during the growth and remodeling of the skeleton are called

Options

A. Osteocytes
B. Osteoblasts
C. Osteoctasts
D. osteons

Answer

To answer the question about the cells responsible for the resorption of bone matrix during the growth and remodeling of the skeleton, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Bone Remodeling**: Bone remodeling is a continuous process where old bone is replaced by new bone. This process involves different types of cells that have specific functions.

2. **Identify the Types of Bone Cells**:
- **Osteoblasts**: These are the cells responsible for forming new bone. They synthesize and secrete the bone matrix.
- **Osteocytes**: These are mature bone cells that originate from osteoblasts. They maintain the bone matrix but do not play a direct role in resorption.
- **Osteoclasts**: These are large cells that break down bone tissue. They are involved in the resorption of bone matrix.

3. **Focus on Resorption**: The question specifically asks for the cells responsible for the resorption of bone matrix. Among the three types of cells identified, the osteoclasts are the ones that break down bone tissue and facilitate the resorption process.

4. **Conclusion**: Based on the functions of the different bone cells, the correct answer to the question is that the cells responsible for the resorption of bone matrix during the growth and remodeling of the skeleton are called **Osteoclasts**.

### Final Answer:
The cells responsible for the resorption of bone matrix during the growth and remodeling of the skeleton are called **Osteoclasts**.
