Describe osteoporosis and what type of bone cell the patient would be lacking?
Occurs when bone tissue degenerates faster than it is replaced. The bones become weakened and brittle, bones cause pain and can fracture easily. Osteoblasts, responsible for bone repair, would decrease meaning that bone repair would not be able to keep up with the ongoing breakdown of bone.
Explain what it means to have a herniated disc and discuss one treatment option to address pain
