Which of the following is the predominant cell type in connective tissue proper?

Options

A. Fibroblasts
B. Lymphocytes
C. macrophages
D. Mast cells

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the predominant cell type found in connective tissue proper. Connective tissue is one of the four main types of tissues in the body, and it serves various functions including support, binding, and protection.

2. **Identifying the Options**: The options provided are:
- A) Fibroblast
- B) Lymphocyte
- C) Macrophages
- D) Mast cell

3. **Analyzing Each Option**:
- **Fibroblast**: These are the most common cells in connective tissue proper. They are responsible for producing fibers (like collagen and elastin) and the ground substance of the extracellular matrix.
- **Lymphocyte**: These are a type of white blood cell involved in the immune response, not predominantly found in connective tissue proper.
- **Macrophages**: These are immune cells that help in phagocytosis but are not the predominant cell type in connective tissue proper.
- **Mast cell**: These cells are involved in allergic responses and inflammation but are not the main cell type in connective tissue proper.

4. **Conclusion**: Based on the analysis, the predominant cell type in connective tissue proper is **A) Fibroblast**. They play a crucial role in maintaining the structure and integrity of connective tissues by producing fibers and the extracellular matrix.

5. **Final Answer**: The correct answer is **A) Fibroblast**.
