Question

Quizplus · Accepted Answer

The elastin core in elastin fibers is covered with a sheath of microfibrils which are elastic in their own right and seem to provide scaffolding to guide elastin deposition in developing tissues. Fibrillin is a glycoprotein in microfibrils that is essential for the integrity of elastic fibers.
