Which of the following is NOT a component of hyaline cartilage?
A
Ground substance
B
Elastic fibers
C
Collagen fibers
D
Chondrocytes
Verified step by step guidance1
Step 1: Begin by understanding the structure and composition of hyaline cartilage. Hyaline cartilage is a type of connective tissue found in areas such as the nose, trachea, and ends of long bones. It provides support and reduces friction in joints.
Step 2: Identify the components of hyaline cartilage. Hyaline cartilage is primarily composed of chondrocytes (cartilage cells), collagen fibers (specifically type II collagen), and ground substance (a gel-like matrix containing proteoglycans and water).
Step 3: Review the role of elastic fibers in cartilage. Elastic fibers are primarily found in elastic cartilage, not hyaline cartilage. Elastic cartilage is found in structures like the external ear and epiglottis, where flexibility is required.
Step 4: Compare the options provided in the question. Ground substance, collagen fibers, and chondrocytes are all components of hyaline cartilage, while elastic fibers are not.
Step 5: Conclude that the correct answer is 'Elastic fibers,' as they are not a component of hyaline cartilage.
