Answer:
True
Explanation:
Elastic fibers are composed of elastin, myofibrils and fibrillin. They are distributed <u>separately</u>, and therefore do not form bundles(they actually form a kind of mesh), like collagen fibers.
Elastic fibers are usually thin and long and can stretch up to 1.5x of their total length.
These fibers confer elasticity to the connective tissue. The mesh formed of elastic fibers easily yields to minimal tensions, returning to its original shape as soon as the deforming forces cease.
An example of the action of elastic fibers is when we pull the skin from our hands and release it, the elastic fibers are responsible for quickly returning the skin to its original shape.
