Which of the following structures contribute most to the tensile strength of loose connective tissues?

Options

A. Elastic fibres
B. Myofibrils
C. Collagen fibres
D. Chondrin

Explanation

**Step-by-Step Solution:**

1. **Understanding Connective Tissue**:
- Connective tissues are a group of tissues that connect or bind other tissues in the body. They play a crucial role in providing support and structure.

2. **Types of Connective Tissue**:
- There are two main types of connective tissue: dense connective tissue and loose connective tissue.
- Loose connective tissue includes areolar tissue, reticular tissue, and adipose tissue.

3. **Function of Loose Connective Tissue**:
- The primary function of loose connective tissue is to hold organs in place and attach epithelial tissue to underlying tissues.

4. **Key Components of Loose Connective Tissue**:
- Loose connective tissue is characterized by the presence of collagen fibers, which are essential for its structure and function.

5. **Understanding Collagen Fibers**:
- Collagen fibers are made up of collagen, which is a hard, insoluble, and fibrous protein.
- These fibers provide strength and elasticity to the tissue.

6. **Identifying the Answer**:
- The question asks which structure contributes most to the tensile strength of loose connective tissues.
- Among the options provided (elastic fibers, myofibrils, collagen fibers, or chondrites), collagen fibers are the most significant contributors to tensile strength.

7. **Conclusion**:
- Therefore, the correct answer is **collagen fibers**.
