Bone: intramembranous formation
Intramembranous bone formation in the fetus can produce compact, as well as spongy bone, as seen in this image from the diaphysis of a fetal, long bone. The lack of lamellae, the blue tint to the matrix and the rounded, numerous osteocytes are all indicative of woven bone. 200x
