It is just my curiosity. I wanted to see a dissection of a long bone to see how the yellow bone marrow looks like. I looked at the video showing a blood sample under the microscope to see red, white cells and platelets. I looked at bones and muscles in 3D, googled the ear bones pictures.
I want you to avoid spending time 'Googeling' any course material. What do you need? Which images? Which videos?
