Which cell of connective tissue, produce and secrete fibres ?

Options

A. Mast cell
B. Fibroblast
C. Macrophage
D. Adipocytes

Answer

**Step-by-Step Solution:**

1. **Understanding Connective Tissue**: Connective tissue is a type of tissue that supports, binds together, and protects tissues and organs of the body. It consists of various cell types and extracellular matrix.

2. **Identifying Cell Types**: In connective tissue, there are several types of cells, including mast cells, fibroblasts, and adipocytes.

3. **Analyzing Mast Cells**: Mast cells are involved in the immune response and are known for releasing histamine and heparin. However, they do not produce or secrete fibers.

4. **Identifying Fibroblasts**: Fibroblasts are the primary cells responsible for producing and secreting fibers in connective tissue. They synthesize collagen, elastin, and other extracellular matrix components that provide structural support.

5. **Considering Adipocytes**: Adipocytes, or fat cells, are specialized for storing energy in the form of fat. They do not produce fibers.

6. **Conclusion**: The cell of connective tissue that produces and secretes fibers is the **fibroblast**.

**Final Answer**: Fibroblast cells are responsible for producing and secreting fibers in connective tissue.
