Do toes contain bone marrow?
no, only in your larger bones like legs and arms
Bone marrow comes in two categories, red and yellow. Red is common in young children's bones. It creates red blood cells. As you become a teenager, you have less red and more yellow bone marrow. Yellow bone marrow stores fat so it can later be used as energy, but there are still some bones that contain red bone marrow.
As children, nearly all of our bones contain red bone marrow, but this gradually gets replaced by yellow marrow as we grow older. As adults, red bone marrow is found mainly in the axial skeleton (skull, spine and rib cage) and girdles (pelvis and shoulders) and at the ends (epiphyses) of the humerus and femur.
