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

Options

A. Striated muscle
B. Areolar tissue
C. Stratified epithelium
D. Neuroglia

Answer

To determine which option contains the largest quantity of extracellular material, we can analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Extracellular Material**:
- Extracellular material refers to substances found outside the cells, primarily in connective tissues. This includes proteins, fibers, and ground substance that provide structural and functional support to tissues.

2. **Analyzing the First Option - Striated Muscle**:
- Striated muscle, also known as skeletal muscle, is primarily composed of muscle fibers (cells).
- **Conclusion**: Striated muscle has minimal extracellular matrix, making this option incorrect.

3. **Analyzing the Second Option - Areolar Tissue**:
- Areolar tissue is a type of loose connective tissue that contains a significant amount of extracellular matrix.
- It consists of various fibers (collagen, elastic, and reticular) and cells (fibroblasts, macrophages, plasma cells, adipocytes, and mast cells).
- **Conclusion**: Areolar tissue has a large quantity of extracellular material, making this option correct.

4. **Analyzing the Third Option - Stratified Epithelium**:
- Stratified epithelium is a type of epithelial tissue that forms protective layers.
- Epithelial tissues generally have very little extracellular matrix as they are primarily composed of tightly packed cells.
- **Conclusion**: This option is incorrect due to the absence of significant extracellular material.

5. **Analyzing the Fourth Option - Neuroglia**:
- Neuroglia, or glial cells, support neurons in the nervous system.
- Similar to epithelial tissue, neuroglia has minimal extracellular matrix.
- **Conclusion**: This option is also incorrect.

### Final Answer:
The option that contains the largest quantity of extracellular material is **Areolar Tissue** (Option 2).
