Osteomalacia Osteoporosis

Compare and contrast the causes and changes associated with osteoporosis, osteomalacia and Paget's diease

This is a very involved for only two points!

But anyway, you should be able to find some good info on the internet - ie everyone has a Wikipedia page, and there are bound pages of pathology services and classes that provide descriptions and histology. In addition, a good library should have a medical condition book that you can watch these things in. You might even find a useful reference work in a big book store.

You can also try to ask the question under the medicine instead of science = maybe an MD will give a good answer there.

HTH.
