What’s in a Bone?

A couple of weeks ago we started learning about the brain and bones. When talking about the bones, we first made a model of our spine so we could see how the spinal cord ran through the center of all the vertebrae that make up our spine and how it could move.  Then, we dissected a cow femur bone! We started by learning about the different parts that make up every bone in the body. The Periosteum is the outer covering of the bone, then there is spongy and compact bone. In the center is the marrow. We were surprised that all of the different parts of the bone look so different under the microscope. We were also surprised at how much it smelled… :0x After looking on-line for information about the marrow and what it does, we found recipes for ways to cook and EAT the marrow on BREAD!!!? We did not do this!

Did you know we have 206 bones in our body? That’s so many!
