The organic portion of matrix is important in providing all but
a. Tensile strength
b. Hardness
c. Ability to resist stretch
d. Flexibility

검증된 단계별 안내
1
Understand that the organic portion of the matrix in connective tissues, such as bone, primarily consists of collagen fibers and ground substance, which contribute to properties like tensile strength, flexibility, and the ability to resist stretch.
Recall that tensile strength refers to the ability to resist pulling forces, which collagen fibers provide effectively.
Recognize that flexibility and the ability to resist stretch are also characteristics imparted by the organic matrix due to the nature of collagen and other organic components.
Identify that hardness is generally a property provided by the inorganic portion of the matrix, mainly composed of mineral salts like calcium phosphate, which give rigidity and hardness to structures like bone.
Conclude that among the options, hardness is the property not provided by the organic portion of the matrix.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Organic Matrix in Bone

The organic matrix of bone primarily consists of collagen fibers and ground substance, which provide the bone with flexibility and tensile strength. This matrix allows bones to resist stretching and bending forces, contributing to their overall resilience.

Tensile Strength

Tensile strength refers to the ability of a material to withstand pulling or stretching forces without breaking. In bones, the organic matrix, especially collagen, is responsible for providing this property, allowing bones to endure tension.

Hardness in Bone

Hardness is the resistance of a material to deformation or scratching, primarily provided by the inorganic mineral components like hydroxyapatite in bone. The organic matrix does not contribute significantly to hardness, which is why it is not associated with this property.
