  • Consists of a long shaft
  • Yellow marrow contains fat cells and leukocytes.
  • Red marrow produces erythrocytes and leukocytes.
  • All bones in upper and lower limbs are long bones except patella, carpals and tarsals.
• Bone

  • Living tissue
  • Compact bone consists of dense tissue and forms the surface of bones. They provide strength and support.
  • Spongey tissue consists of softer tissue and forms the heads of long bones and contain red marrow. They exert resistance against forces that act on the bone.
• Cartilage

  • A tough, elastic connective tissue.
  • Protects joints and facilitates movement.
• Tendons

  • Inelastic connective tissue
  • Attach muscles to bones.
  • Inelasticity allows for the contraction & relaxation of muscles, facilitating movement.
• Ligaments

  • Consist of tough, elastic connective tissue.
  • Attach bone to bone.
  • Stretch enough to control movement in a joint.
  • Stabilise joints.
