1a. What type of bony tissue do you suppose the initial callus will be composed of?
1b. What will the final repaired area be-compact or spongy?
1c. Which type of bone is easier to produce?
1d. Which type of bone would be stronger?
Homework Answers
a. Initial callus is composed of both hyaline and fibrocartilage
b. The fibrocartilaginous callus is converted into a bony callus of spongy bone.
c. Cancellous bone is made up of spongy, porous, bone tissue that is filled with red bone marrow. It is not as strong as cortical bone, which is found in the long bones, but it is very important for producing blood cells.
d. Compact bone is the heaviest and hardest type of bone. It needs to be very strong as it supports the body and muscles. About 80% of the bone in the body is compact. It makes up the outer layer of the bone and also helps protect the more fragile layers inside.
