Matrix of the connective tissue is secreted by

Options

A. Fibrocytes
B. Histiocytes
C. Mast cells
D. Plasma cells.

Explanation

**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 plays a crucial role in the organization and formation of various parts of organs.

2. **Identifying the Matrix**: The matrix of connective tissue is the non-cellular component that provides structural and biochemical support to the surrounding cells. It consists of fibers (like collagen and elastin) and ground substance.

3. **Role of Fibrocytes**: The primary cells responsible for the secretion of the matrix in connective tissue are called fibrocytes (or fibroblasts). These cells produce and maintain the extracellular matrix, which is essential for the structural integrity of connective tissues.

4. **Minor Contributions**: While fibrocytes play the major role in matrix secretion, other cells, such as mast cells, may have a minor role in the overall function and maintenance of the connective tissue.

5. **Conclusion**: Therefore, the matrix of connective tissue is primarily secreted by fibrocytes.

**Final Answer**: The matrix of connective tissue is secreted by fibrocytes.
