Histo-Tips: When trying to differentiate between veins and arteries, look for clearly defined layers (usually arteries) or the size of the lumen (usually collapsed in veins).
You are showing compact bone here, not an intramembranous ossification. Please go back and take a different picture to show the intramembranous ossification. It may be hard to find- look around for different slides (I believe we found some in slide 95 in some boxes). You will find it near the skull, and you should see mesenchymal cells condensing into bone. What you have shown is bone that is already formed.
