Anatomy ch. 5 bone remodeling steps

2nd step of bone remodeling

activation phase; the pre-osteoclasts become fused and form multinucleated osteoclasts

5th step of bone remodeling

after the pit is completed, the osteoclasts disappear

4th step of bone remodeling

as the pit is being dug out calcium can be released into the blood for use by the body

1st step of bone remodeling

during the activation phase, the pre-osteoclasts are attracted to the remodeling sites

8th step of bone remodeling

during the formation phase, the pre-osteoblasts mature into osteoblasts at the surface of the burrow pit

3rd step of bone remodeling

during the resorption phase, the osteoclasts dig out a cavity called a resorption pit

6th step of bone remodeling

in the reversal phase, mesenchymal stem cells appear along the burrow or pit

7th step of bone remodeling

the cells along the pit increase in number and become specialized into pre-osteoblasts

9th step of bone remodeling

the osteoblasts busy themselves by releasing osteoid (a soft, nonmineralized bone matrix)

11th step of bone remodeling

the remodeling site (now new bone tissue) remains resting/quiescence until the next bone remodeling cycle begins

10th step of bone remodeling

this phase must be called the formation phase because the new matrix becomes mineralized with calcium and phosphorus thus creating new bone
