In bone, this part of the process is accomplished by osteoclasts, which make their way into the calcifying cartilage and take bone out of the middle of the shaft, leaving room for marrow to form. Osteoclasts do this by engulfing and digesting the bone matrix using acids and hydrolytic enzymes...

The test shows much more detail of the bones than regular X-rays, and it can help diagnose bone problems and find breaks in bones that X-rays may not pick up. Bone scan. This test creates images of bones on a computer screen or film. First, you’ll get a harmless radioactive ...
Arthrocentesis is often performed in the doctor's office. During arthrocentesis, a sterile needle is used to remove joint fluid for analysis. Joint fluid analysis is useful in excludinggout, infection, and other causes of inflammatoryarthritis. Removal of joint fluid and injection of corticosteroid...
