Compare and contrast the three types of fibers found in the extracellular matrix

Question

What will be an ideal response?

Answer 1

A complete response should include these concepts:
• Collagen
• A strong, inelastic fiber
• Provides stability to the fascial network
• Forms thick, ropelike structures, with a white color
• The ratio of collagen fibers in a given area of fascia depends on the general amount of stress applied to it.
• Elastin
• Long, thin fibers that can stretch and recoil
• Lends a flexible element to fascia
• Are found in branched networks throughout the matrix and have a yellow color
• The fascia associated with tissues that need a higher degree of flexibility, such as those of the lungs, have a higher ratio of elastin.
• Reticulin
• Is an altered form of collagen fiber that is much smaller and finer
• Forms a spongelike mesh that creates spaces in the fascia
• The "mesh" provides room for structures such as lymph and blood vessels and also connects the layers of fascia together.
