this bone cell type is a specialized macrophage
T/F both periosteal and endosteal surfaces are completely lined with cells
how is an osteoclast formed?
from fusion of multiple monocytes
how to identify osteoclast?
large and multinucleated on surface of bone

2 layers of periosteum
cellular (bone lining cells)
fibrous layer (condensed fibrous layer)
how can you identify an osteoprogenitor cell?
will look like bone lining cell, can't really tell difference

T/F normal adult hyaline cartilage is avascular
(blood supply brings calcium and triggers mineralization of cartilage matrix in endochondral ossification)
clusters of chondrocytes
formed from parent chondrocyte and all hang around together
what is the appearance of isogenous groups in the epiphyseal growth plate? why?
because matrix is growing in one direction
