Which statement best describes the matrix of hyaline cartilage?
A
It is composed mainly of elastic fibers and a fluid ground substance.
B
It consists primarily of reticular fibers and a hard, calcified matrix.
C

D
It contains abundant collagen fibers hidden in a rubbery matrix.
Verified step by step guidance
1
Step 1: Understand the structure and composition of hyaline cartilage. Hyaline cartilage is a type of connective tissue that provides support and flexibility. Its matrix is specialized to allow smooth movement at joints and resist compression.
Step 2: Learn about the components of the matrix. The matrix of hyaline cartilage is primarily composed of collagen fibers, which provide strength, and a rubbery ground substance made of proteoglycans and water, which gives it resilience and flexibility.
Step 3: Compare the descriptions provided in the problem. Analyze each option to determine which one accurately describes the matrix of hyaline cartilage. For example, elastic fibers are characteristic of elastic cartilage, not hyaline cartilage.
Step 4: Eliminate incorrect options. Reticular fibers and a hard, calcified matrix are features of bone tissue, not hyaline cartilage. Dense bundles of fibroblasts and adipocytes are associated with other connective tissues, such as adipose tissue or dense connective tissue.
Step 5: Select the correct answer based on the characteristics of hyaline cartilage. The correct description is that the matrix contains abundant collagen fibers hidden in a rubbery matrix, which aligns with the structural and functional properties of hyaline cartilage.
