Which two primary fibers are found within fascia?

• A. Cytokinins and glycoproteins
• B. Collagen and elastin
• C. Actin and myosin
• D. Creatine and keratin

Answer: (B)

The presence of collagen and elastin in fascia is crucial because they provide the structural integrity and elasticity that fascia requires to function properly. Collagen fibers are strong and provide tensile strength, allowing fascia to resist stretching and provide support to muscles and organs. This strength is vital in maintaining the shape and stability of the body's structures. Elastin fibers, on the other hand, contribute to the flexibility and resilience of fascia. This allows fascia to stretch and return to its original shape, which is necessary for accommodating movements and maintaining proper range of motion. In contrast, the other options contain fibers that are not primarily associated with fascia. Cytokinins and glycoproteins are involved in cellular signaling and interactions, but they do not make up the structural framework of fascia. Actin and myosin are muscle contractile proteins, not components of fascia. Creatine is related to energy metabolism in muscles, and keratin is a structural protein mainly found in hair and nails. Therefore, the combination of collagen and elastin is essential for the functional properties of fascia, making it the correct answer.
