Here is the exam review for our next major lecture exam which will be on Monday. Notice that there are a few things missing, such as endochondral ossification. These will be added so just because it does not show up on this exam review doesn't mean you shouldn't study it. That being said, the details of each and every bone which I've gone over in lecture will be on the lab practical rather than the written lecture exam.
