Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Of the three connective tissue fibers, which one provides the greatest flexibility (because of its ability to stretch)?
A
Collagen
B
Elastic
C
Reticular
D
None of the above
Explanation: 

Detailed explanation-1: -Elastic fibers are made of the protein elastin; this fiber can stretch to one and one half of its length and return to its original size and shape. Elastic fibers provide flexibility to the tissues. Reticular fibers are the third type of protein fiber found in connective tissues.

Detailed explanation-2: -Collagen: Collagen fibers are the strongest and most abundant of all the connective tissue fibers. Collagen fibers are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix.

Detailed explanation-3: -Elastin is a protein that exists as fibers in the extracellular spaces of many connective tissues. Elastin derives its name from its ability to act as an elastic band, that is, to stretch and recoil with transient force.

Detailed explanation-4: -Dense connective tissue contains more collagen fibers than loose connective tissue. Dense regular connective tissue (Figure 4) has fibers arranged in neatly organized, parallel bundles. It has both collagen and elastic fibers, which provide great tensile strength and elasticity in one direction.
