A patient has a diagnosis of osteoporosis. (1) In your own words, describe this diagnosis and (2) What type of bone cell would they be lacking? Explain your answer.
Your Answer:
osteoporosis is a bone disease: basicly causing bone tissue to degenerate faster than it can be replaced. This will cause pain and prone to fx. There is a lack of osteoblast and osteoblast to repair bones.
(1) Osteoporosis is a bone tissue disease. When bone tissue degenerates faster than is replaced, the bones become weak. Brittle bones cause increased pain and are more likely to fracture.
(2) They would have decreased osteoblasts which are responsible for bone repair. The bone repair would be unable to keep up with the ongoing breakdown of bone which is done by the work of osteoblasts.
