Question

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

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

Answer 1

The Correct Option is B

To determine which of the given options contains the largest quantity of extracellular material, we need to understand what extracellular material is and how it relates to each of the options:

1. Striated muscle: This type of muscle tissue is characterized by a pattern of stripes, known as striations, and includes skeletal and cardiac muscles. These tissues have a limited amount of extracellular matrix, as they are composed primarily of tightly packed muscle fibers.
2. Areolar tissue: This is a type of connective tissue that provides support and elasticity to various internal organs. It contains a high amount of extracellular material, which includes a mix of collagen fibers, elastic fibers, and a jelly-like ground substance. It acts as a packing material around organs and under the skin.
3. Stratified epithelium: This type of tissue is composed of multiple layers of epithelial cells, which serve as protective barriers. They have very little extracellular material, as the cells are tightly packed together to form protective layers on body surfaces.
4. Myelinated nerve fibres: These fibers are axons of neurons wrapped in myelin sheath, which helps in the rapid transmission of nerve impulses. The extracellular material is minimal, primarily limited to the space between the myelin sheath and surrounding tissues.

Based on this analysis, areolar tissue contains the largest quantity of extracellular material. It has a significant amount of ground substance which provides a cushioning and supportive environment for various structures.

Therefore, the correct answer is Areolar tissue.
