Which one of the following contains the largest quantity of extra-cell...
Answer: B. Areolar tissue
Explanation:
- Striated muscle: This type of muscle is mainly found in skeletal muscles, and its primary function is to facilitate movement. It contains a limited amount of extracellular material as it is composed mainly of muscle fibers and is packed densely.
- Areolar tissue: This is a type of loose connective tissue that is found between various organs and tissues in the body. It is characterized by a large amount of extracellular material, which includes fibers (collagen, reticular, and elastic) and ground substance. This tissue helps to provide support, flexibility, and cushioning to the surrounding structures, making it the correct answer.
- Stratified epithelium: This is a type of epithelial tissue composed of multiple layers of cells, which functions mainly as a protective barrier. It contains very little extracellular material, as the cells are tightly packed together.
- Myelinated nerve fibers: These are nerve fibers surrounded by a myelin sheath, which is a fatty substance that insulates the fibers and allows for faster transmission of nerve impulses. The extracellular material in this case is limited to the small spaces between the fibers.
In summary, areolar tissue contains the largest quantity of extracellular material among the given options, as it serves to provide support and flexibility to various organs and tissues in the body.
Which one of the following contains the largest quantity of extra-cell...
Explanation:
Extra-cellular material refers to the material present outside of the cells in a tissue or an organ. It includes the extracellular matrix, connective tissue fibers, and fluids. The quantity of extra-cellular material varies among different tissues and organs.
Areolar tissue:
Areolar tissue is a loose connective tissue that contains a large amount of extra-cellular material. It is found beneath the skin, around blood vessels and nerves, and in various organs. The extra-cellular material in areolar tissue includes fibrous proteins, glycosaminoglycans, and fluid. It provides support and elasticity to the organs and helps in the exchange of nutrients and wastes.
Striated muscle:
Striated muscle is a type of muscle tissue that contracts and relaxes to produce movement. It contains a significant amount of extra-cellular material in the form of connective tissue fibers and fluids. However, the quantity of extra-cellular material is less compared to areolar tissue.
Stratified epithelium:
Stratified epithelium is a type of tissue that forms the outer layer of the skin and lines the body cavities. It contains a minimal amount of extra-cellular material, mainly in the form of extracellular matrix.
Myelinated nerve fibers:
Myelinated nerve fibers are nerve fibers that are wrapped in a myelin sheath. They contain very little extra-cellular material, mainly in the form of interstitial fluid.
Conclusion:
Based on the above explanation, it can be concluded that areolar tissue contains the largest quantity of extra-cellular material among the given options.
