  1. Histology of Bone and Cartilage Dr. Sama ul Haque

  2. Cartilage • Type of Dense connective tissue ( Cells and fibers) • Perichondrium ( Fibro-vasculo-cellular membrane) • Cells = Characterized by Rigid with flexibility and Resilience. • Avascular • Nerves and lymphatics are absent • Cells (Chondroblasts and chondrocytes) • Matrix => Connective tissue fibers (Collagen, Elastin)

  3. Hyaline Cartilage • Hyaline (Glass) • Commonest form • Bluish white, translucent and homogenous in appearance with collagen fibers. Sites: => Articular cartilage => Costal cartilage => Tracheal cartilage  Ossifies to form bone in young age

  4. Hyaline Cartilage and Perichondrium

  5. Elastic Cartilage • Yellow; Elastin fibers • More elastic than hyaline • Sites: => Pinna of the ear => Epiglottis => Auditory tube  Never ossifies

  6. Elastic Cartilage

  7. Fibro-cartilage • White, Opaque with collagen fibers • Sites => Intervertebral disc => Intra articular disc => Menisci  Ossifies in old age

  8. Fibrocartilage • Collagen (c)

  9. Cartilages
