Which type of connective tissue fiber is referred to as "white fibers"?

The type of connective tissue fiber referred to as "white fibers" is collagenous fibers. These fibers are composed primarily of collagen, a protein that provides strength and structural support to various tissues and organs in the body. Collagenous fibers are generally thicker and have a high tensile strength, which is why they are associated with the term "white fibers." They can withstand stretching and are abundant in tendons, ligaments, and the dermis of the skin, contributing to the overall integrity and resilience of connective tissues.

The term "white fibers" is used because collagen fibers appear white in color when fresh and are described as non-elastic, unlike elastic fibers, which are more flexible and allow tissues to stretch and recoil. This distinction is essential in understanding the various functional properties of connective tissues and their respective fibers.
