      • Bone (osseous) Connective Tissue
        • Cells
          • Osteoprogenitor cells (stem cells)
          • Osteoblasts
          • Osteocytes (in lacunae)
          • Osteoclasts
        • Matrix

        • Matrix: arranged as lamellae
          • Collagen fibers
          • Calcium phosphate salts (as hydroxyapatite)

      • Arrangements of Bone Tissue
        • Compact (cortical)
        • Spongy (cancellous)

      • Compact Bone Tissue
        • Location
          • On bone surfaces (matrix arranged as circumferential lamellae)
          • In shafts of long bones (matrix arranged as concentric

      • Arrangements of Bone Tissue
        • Compact Bone Tissue
        • Spongy (cancellous) bone tissue
          • Location: within bones
          • Consists of branching plates called trabeculae
          • Bone marrow found between the trabecular spaces
