Question

how is hyaline cartilage different from elastic cartilage or fibrocartilage?
it allows great flexibility.
it contains more nuclei.
it is more vascularized.
fibers are not normally visible.

Explanation:

• Hyaline cartilage has a matrix with fine collagen fibers that are not easily visible under a light microscope.
• Elastic cartilage has elastic fibers (in addition to collagen) which give it great flexibility.
• Fibrocartilage has thick bundles of collagen fibers.
• All types of cartilage (hyaline, elastic, fibrocartilage) are avascular (no blood vessels) and chondrocytes (cartilage cells) have a single nucleus (not more nuclei in hyaline compared to others in a way that differentiates them as per the question).

Answer:

Fibers are not normally visible.
