compact bone structure

osteons

circle columns that make the bones (there’s multiple that make the bone)

• anti bending and twist

• structure

• helps repair

lamellae

thin layer (rings) that surround the central canal

• help distribute force equally

• strength

circumferential lamellae

the layer (rings) that surround the entire inner and outer surface rather than a single osteons

• provides overall structure

central canal

the hallow tube at the center of each osteon

• pathway for nutrients and oxygen

• removes waste and helps communication

lacunae

the dark circles around the rings (houses an osteocyte)

• keep osteocytes in place

canaliculi

tiny hair like structure from the lacunae(it’s that makes them look like little spiders)

-cell communication

osteocytes

mature bone cell, caretaker of the bone

do NOT divide , maintain bone

signal remodeling

perforating canals

tunnels that run horizontal

• connects central canals

• link blood vessels and nerve of the periosteum to inside of bone
