Which of the following is a characteristic feature of areolar connective tissue?

• A. Lacks blood vessels and is avascular
• B. Composed primarily of densely packed collagen fibers
• C. Contains loosely arranged fibers and abundant ground substance
• D. Contains only one type of cell, the adipocyte

Answer: (C)

Verified step by step guidance

1. Understand the structure and function of areolar connective tissue: Areolar connective tissue is a type of loose connective tissue that provides support and flexibility to surrounding tissues. It is characterized by loosely arranged fibers and abundant ground substance.
2. Review the components of areolar connective tissue: It contains various types of cells, such as fibroblasts, macrophages, mast cells, and adipocytes, along with extracellular matrix components like collagen, elastic, and reticular fibers.
3. Clarify the vascularity of areolar connective tissue: Unlike avascular tissues (e.g., cartilage), areolar connective tissue is highly vascularized, meaning it contains blood vessels that supply nutrients and oxygen to the cells.
4. Compare areolar connective tissue to other connective tissues: Dense connective tissues, such as tendons and ligaments, are composed primarily of densely packed collagen fibers, whereas areolar connective tissue has loosely arranged fibers and abundant ground substance.
5. Identify the correct characteristic: Based on the description, the defining feature of areolar connective tissue is its loosely arranged fibers and abundant ground substance, which distinguishes it from other types of connective tissue.
