Woven bone. Osteoblasts (short arrow) and osteoclasts (long arow) are abundant, cement lines irregular
--first show up in early development or when trying to repair
--in adult structures like the alveolus of the tooth
--has a lot of osteoblast
Lamellar bone. Note the parallel cement lines and lack of cellular activity—no osteoblast or osteoclast
Will see the bone marrow
-- (do a bone marrow aspirate—in sternal area, hip area)—getting a piece of tissue
normo cellular bone marrow
--higly meatbolic factory
--white cells are fat cells
High power view of marrow
--see normoblastic or erythroblastic cells
--white cells—fat (must be in balace--not too much or too little)
---see precurosr myeloid cells—look like horse shoe
