• TISSUES WITH LIQUID MATRIX:
  • BLOOD (Contains erythrocytes, leucocytes, platelets, & plasma)
  • LYMPH (Contains leucocytes and plasma only)
• TISSUES WITH SOLID OR SEMISOLID MATRIX:
  • "LOOSE" CONNECTIVE TISSUE (non-calcified, few fibers)
    • Mesenchyme (embryonic connective tissue)
    • Areolar (loose "ordinary") connective tissue
    • Reticular connective tissue
    • Adipose (fat) tissue
  • "DENSE" CONNECTIVE TISSUE (non-calcified, many fibers)
    • Dense, regular connective tissue (e.g., tendons, ligaments)
    • Dense, irregular connective tissue (e.g., dermis of skin)
    • Reticular connective tissue
  • HEMOPOIETIC (blood-forming) TISSUE
    • Lymphoid tissue
    • Red myeloid tissue (red marrow)
    • Yellow myeloid tissue (yellow marrow)
  • STRUCTURAL (HARDENED) CONNECTIVE TISSUES
    • Cartilage tissue
      • Hyaline cartilage
      • Fibrocartilage
      • Elastic cartilage
      • Calcified cartilage
    • Bone tissue
      • Compact bone tissue
      • Cancellous (spongy) bone tissue
    • Dentine
    • Enamel
