Answer to Question 1

ANS: B
The elbow joint is freely moveable and is an example of a diarthrosis joint; amphiarthrosis joints are only slightly moveable. Synarthrosis joints are immoveable. A symphysis is a cartilaginous joint in which bones are united by a pad or disk of fibrocartilage.

Answer to Question 2

ANS: B
Osteoblasts are the bone-forming cells. Their primary function is to lay down new bone. Once this function is complete, osteoblasts become osteocytes. Osteoclasts reabsorb bone.
Chondroblasts are a part of mature bone. Osteoids are part of nonmineralized bone matrix that the osteoblasts work on.
