Which one of the following contains the largest quantity of extracellular material ?

Options

A. Striated muscle
B. Areolar tissue
C. Stratified epithelium
D. Myelinated nerve fibres

Explanation

To determine which option contains the largest quantity of extracellular material, we will analyze each of the given options: striated muscle, areolar tissue, stratified epithelium, and myelinated nerve fibers.

### Step-by-Step Solution:

1. **Understanding Extracellular Material**:
- Extracellular material refers to the non-cellular component of tissues, which includes the extracellular matrix. This matrix provides structural and biochemical support to surrounding cells.

2. **Analyzing Striated Muscle**:
- Striated muscle primarily functions to generate force and contract for movement and other physiological functions. The extracellular material present in striated muscle is relatively less compared to other tissues, as the focus is on muscle fibers.

3. **Analyzing Areolar Tissue**:
- Areolar tissue is a type of connective tissue that serves multiple functions, including holding organs in place and acting as a reservoir of water and salts for surrounding tissues. It contains a significant amount of extracellular matrix, which supports various cells.

4. **Analyzing Stratified Epithelium**:
- Stratified epithelium consists of multiple layers of cells primarily serving a protective function. While it does have some extracellular material, it is not as abundant as in connective tissues.

5. **Analyzing Myelinated Nerve Fibers**:
- Myelinated nerve fibers are part of the nervous system and are primarily composed of neurons and glial cells. The extracellular material in this context is minimal, as the focus is on the conduction of nerve impulses.

6. **Conclusion**:
- Among the options, areolar tissue contains the largest quantity of extracellular material due to its role as a connective tissue that supports various structures and contains a significant extracellular matrix.

### Final Answer:
**Areolar tissue contains the largest quantity of extracellular material.**
