Question

The reason that intervertebral discs exhibit a large amount of tensile strength to absorb shock is because they possess ________.

A) hydroxyapatite crystals
B) collagen fibers
C) reticular fibers
D) elastic fibers

Answer 1

Fianl Answer:

The reason that intervertebral discs exhibit a large amount of tensile strength to absorb shock is because they possess collagen fibers.

thus the correct answer is B) collagen fibers.

Step-by-step explanation:

Intervertebral discs, which lie between the vertebrae of the spine, are crucial for providing flexibility and shock absorption. The primary reason for their ability to absorb shock and withstand tensile forces is the presence of collagen fibers. Collagen is a fibrous protein that forms a strong, flexible matrix within the intervertebral discs. The tensile strength of collagen allows the discs to resist pulling forces and maintain structural integrity, making them well-suited for their role in supporting the spine.

Collagen fibers are essential components of connective tissues throughout the body, providing strength and resilience. In the context of intervertebral discs, the collagenous matrix helps distribute mechanical loads and absorb shocks that result from activities like walking, running, or other movements that impact the spine. The organization of collagen fibers within the disc structure contributes to its ability to resist tensile forces, making it a vital feature for overall spinal health.

So,the correct answer is B) collagen fibers.

Answer 2

The reason that intervertebral discs exhibit a large amount of tensile strength to absorb shock is because they posses Collagen fibers. Thus the correct option is B. Collagen fibers.

Step-by-step explanation:

Intervertebral discs are crucial components of the spine that provide flexibility and absorb shock during movements. The primary reason for their remarkable tensile strength, which allows them to effectively absorb shock, lies in the presence of collagen fibers.

Collagen is a fibrous protein that forms a structural framework in connective tissues, imparting strength and resilience. In the context of intervertebral discs, collagen fibers are arranged in a crisscross pattern, creating a sturdy network that can withstand tension forces.

Collagen's tensile strength is a result of its molecular structure. The triple-helix structure of collagen molecules, consisting of three polypeptide chains, forms a robust and resistant configuration.

This molecular arrangement contributes to the ability of collagen fibers to resist stretching forces, making them well-suited for bearing tensile loads. The interaction between collagen fibers and the gel-like matrix in the intervertebral discs enhances their shock-absorbing capacity, as the fibers resist deformation and provide support to the spine under various stresses.

The mechanical properties of collagen fibers can be attributed to their amino acid composition and the cross-linking between adjacent collagen molecules. The abundance of glycine, proline, and hydroxyproline in collagen contributes to its strength and flexibility.

Additionally, the cross-links formed between collagen molecules further reinforce the overall structure, preventing excessive stretching. Therefore, the collagen fibers in intervertebral discs play a pivotal role in ensuring the spine's stability and shock-absorbing capabilities, making option B the correct choice.

Thus the correct option is B. Collagen fibers.
