Chapter 7: Joints Worksheet
1. The place where two or more bones meet is called a joint or an articulation.
2. List the function of joints:
Make movement possible by binding parts of skeletal system that respond to muscle contractions.
Allows for bone growth.
3. What are the three types of joints?
Fibrous, Cartilaginous, Synovial.
4. What is the structural difference between a fibrous and cartilaginous joints?
Fibrous joints connect two bones with fibrous tissue. Cartilaginous joints connect two bones with cartilaginous or fibrocartilaginous tissue.
5. What is the difference in the amount of movement allowed between a fibrous and a cartilaginous joint?
Fibrous joint permit no movement. Cartilaginous joint permits limited movement.
6. The parts of the bones that come together in a joint are covered by a layer of hyaline cartilage.
7. Articular cartilage lies on the subchondral plate, which usually contains spongy (cancellous) bone.
8. Fibrous Connective Tissue bind the articular ends of the bone together.
9. The membrane that covers all surfaces within the joint capsule is the synovial membrane.
10. List the functions of the synovial membrane and synovial fluid.
Synovial membrane covers surface of joint, secretes synovial fluid. Fluid lubricates and provides nutrition.
11. Describe the menisci and their function.
Piece of fibrocartilage embedded in the joint capsule (shock absorber).
