the epiphysis
medullary cavity
the diaphysis
Membrane surrounding a bone is called
endosteum
periosteum
pericardiam
perichondrium
Why is the yellow membrane of the spongy bone yellow?
Because it stores fat
Osteocytes are yellow in general
Calcium is yellow
Because trabeculae has no blood vessels
long bones
