Covered spongy bone on the inside
Thin plates of periosteum
Contains bone marrow between the trabeculae

Inorganic components of bone
Responsible for 92% of bone mass
Responsible for bone hardness and it’s resistance to compression
Mainly calcium phosphates
65% of bone mass
Hydroxyapatites or bone salts
Osteon (Haversian System)
Central channel containing blood vessels and nerves
Weight-bearing, column-like matrix tubes composed mainly of collage
Basic unit of compact bone
Mainly calcium phosphates
Lamella
Basic unit of compact bone
Connect blood and nerve supply of the periosteum to that of the Haversian Canal
Central channel containing blood vessels and nerves
Weight-bearing, column-like matrix tubes composed mainly of collage
Haversian Canal
Connects blood and nerve supply of the periosteum to that of the Haversian Canal
Central channel containing blood vessels and nerves
Basic unit of compact bone
Calcium phosphates are made from here
Volkmann’s Canals
Connects blood and nerve supply of the periosteum to that of the Haversian Canal
Central channel containing blood vessels and nerves
Weight-bearing, column-like matrix tubes composed mainly of collagen
Canal that’s made out of instruments
Lacunae
Growing bone cells
Hairlike canals that connect lacunae to each other and the central canal
Mature bone cells
Small cavities in bone that contain osteocytes
Canaliculi
Mature bone cells
Small cavities in bone that contain osteocytes
Hairlike canals that connect lacunae to each other and the central canal
Growing bone cells
Osteogenesis or ossification
Process of bone formation
Process of bone tissue formation
Process of bone cell formation
Process of bone cartilage formation
What does osteogenesis or ossification lead to
Homeostatic mechanisms: bone thinness, no modeling, and no repair
Homeostatic mechanisms: bone thickness, remodeling, and repair
Formation of the bony skeleton in embryos
Bone growth until early adulthood
Bone growth that starts after premenopausal
