What characteristic do elastic fibers provide to connective tissues?

• A. Rigidity
• B. Strength
• C. Flexibility
• D. Support

Answer: (C)

Elastic fibers are specialized structures found in connective tissues that confer a unique quality of flexibility. They allow tissues to stretch and then return to their original shape, which is essential for the functioning of certain organs and structures in the body, such as the lungs, arteries, and skin. This property enables organs that must expand and contract during their operations to maintain their integrity and function effectively.

In contrast to rigidity, which would inhibit movement and flexibility, elastic fibers specifically contribute to a tissue's ability to withstand stretching forces while retaining its shape. Although they do provide some support and strength, their primary distinguishing characteristic is their ability to enable tissues to stretch and recoil, making flexibility the most accurate description of the role elastic fibers play in connective tissues.
