Hyaline Cartilage

Key:

  1. Adipose tissue
  2. The tissue to look at – Hyaline Cartilage
  3. Chondrocytes (Cartilage cells) *The purple staining material around the cells is the matrix*

Description:

  • Firm matrix containing Glucosamine and Chondroitin sulfates (Ever heard of the supplements?)
  • Collagen fibers form an imperceptible network
  • Chondroblasts [3] produce (build) the matrix and when mature, they sit in lacunae
  • Has shiny appearance which lends to its ‘low friction’ properties

Function:

  • Provides stiff, but somewhat flexible support
  • Resists compressive stresses (cushioning)
  • Reduces friction between bony surfaces

Location:

  • Forms most of embryonic skeleton
  • Covers ends of long bones
  • Forms costal (rib) cartilage
  • Forms cartilages of nose, larynx, and trachea (helps keep air passages open)
