14. Tip: At 1:11 the bone is pale right next to the bone saw’s cut edge. Below that there is some brown pigment. It looks like a shadow, but it is not. It is pigment. Is the location of the pigment epidural or subdural? How can you tell?
 
 
15. Tip: (Continued) This pigment is called hemosiderin. What is hemosiderin? Why is it there? Correlate the finding with the history. Do you think the hemosiderin is there because of an event before or after the surgery? Or is it related to the surgical procedure itself? Why?
