Down to the Bone

A cow bone that one of the groups dissected. This was a joint so there are 2 different bones in this section of bone.

The Human Biology A class is studying all 206 bones in the body. As part of learning about the bones, the students dissected cow bones on November 3rd to learn the structure of the bones.

Junior Tyler Randall was one of the students that dissected the bones.

“We dissected bones. We had to find the outer layer, the spongy bone, and also the bone marrow that is in the inside,” said Randall. “It was really fun to cut through the muscle because it was easy and soft to cut through. We had to be careful not to cut the bone, because it could break the scalpel,” Randall said.

They had to look at the different layers of the bone and be careful not to cut certain things that would break the scalpel. Marrow in cows is very similar to our bone marrow which is greasy and almost feels like butter.

“The marrow was soft and sticky. It felt like butter and was hard to get off of the tools. We found a tube that was a blood vessel and it was super big. That was cool,” Randall said.

Some things you would never expect to see while dissecting like the blood vessel that Randell and his group saw. The bone structure can be complex to see up close but that’s what makes it so cool.

“It was cool to see the blood come out and to see the different parts of the bone. It was so complicated. It was pretty cool to see how complex it truly was,” Junior Claire Hillier said.
