Cortical Bone Dense, Concentric layers ("osteons" or Haversian systems) Strength - for bearing Weight
Cancellous Bone spongy bone - open Latticework of struts (Trabeculae) Support, transfers energy, Light
Medullary Canal space with the Shaft of bone contains Yellow Marrow for Energy storage
Nutrient Foramina Holes in Compact bone for Larger Blood Vessels
Periosteum layers of Dense Regular Connective Tissue on the Outer surface of bone source of Cells in-case Repair is needed
Haversian Canals Longitudinal channels in bone contain Blood Vessels and Nerve fibers
Osteocytes Mature bone cells trapped in small pockets (Lacunae) Maintain the matrix
Canaliculi Cracks in Matrix connect Lacunae to Haversian Canals
Lamellae Rings of intercellular Matrix contain the Haversian Canals, Osteocytes, and Canaliculi
Osteoblasts Young bone cell Forms bone
Osteoclasts Large bone cell lysosomes dissolve and absorb existing bone (to remodel)
Intramembranous Ossification Hardening within Fibrous Connective Tissue the Formation of the Flat bones of the Skull, Clavicle, and Repair bone Fractures
Endochondral Ossification Replacement of Cartilage replica with Bone cells to Form ALL parts of Skeleton EXCEPT Skull and Clavicles
Red Marrow Myeloid Connective Tissue produces Red and White BC - in Flat bones and Epiphyses of Long bones
