Synovial Joint Quiz
Questions: 16 · 10 minutes
1. A person bends and straightens the elbow during a biceps curl. Which synovial joint type best describes the humeroulnar articulation responsible for this movement?
Saddle joint
Condyloid joint
Pivot joint
Hinge joint
2. A synovial joint permits flexion-extension and abduction-adduction but not axial rotation. How should its movement capacity be described?
Nonaxial
Uniaxial
Biaxial
Multiaxial
3. An athlete sustains a joint sprain without a fracture. Which structure has most likely been overstretched or torn?
The synovial membrane lining the capsule
A tendon connecting muscle to bone
A ligament connecting bone to bone
The articular cartilage covering a bone end
4. Which structure lines most of the capsule's inner surface and produces synovial fluid?
Articular ligament
Synovial membrane
Articular cartilage
Periosteum
5. The carpometacarpal joint at the base of the thumb permits movements important for opposition. How is this joint classified?
Ball-and-socket joint
Plane joint
Pivot joint
Saddle joint
6. A knee meniscus is damaged during a twisting injury. Which normal meniscal function is most directly affected?
Producing synovial fluid for the joint cavity
Connecting skeletal muscle directly to bone
Distributing load and improving fit between articular surfaces
Actively generating knee extension
7. A swollen knee is found to have a joint effusion. What has most directly increased?
The volume of fluid within the joint cavity
The thickness of the periosteum
The length of the cruciate ligaments
The amount of cartilage joining the bones continuously
8. A tendon becomes irritated where it repeatedly passes near a bony prominence. Which synovial structure normally helps reduce friction at such a site?
Ligament
Bursa
Meniscus
Labrum
9. A shoulder injury tears the glenoid labrum. What contribution of the labrum is most likely reduced?
Secretion of synovial fluid into the joint
Attachment of muscle fibers directly to cartilage
Preventing every form of shoulder rotation
Deepening the socket and improving joint stability
10. The radiocarpal joint permits wrist flexion, extension, abduction, and adduction but little axial rotation. Which type is it?
Condyloid joint
Pivot joint
Hinge joint
Plane joint
11. What is a principal function of the fibrous outer layer of an articular capsule?
Enclosing and mechanically reinforcing the joint
Creating the smooth articular surface
Generating the force that moves the joint
Producing blood cells for the joint
12. Small, relatively flat surfaces between neighboring carpal bones primarily glide past one another. Which joint type supports this motion?
Plane joint
Saddle joint
Ball-and-socket joint
Hinge joint
13. In a typical synovial joint, which tissue covers the articulating surfaces of the bones?
Fibrocartilage
Hyaline cartilage
Elastic cartilage
Dense regular connective tissue
14. A joint allows flexion, extension, abduction, adduction, rotation, and circumduction. Which classification best fits this movement pattern?
Hinge joint
Plane joint
Ball-and-socket joint
Condyloid joint
15. Turning the head from side to side mainly involves rotation at the median atlanto-axial joint. What type of synovial joint is it?
Plane joint
Pivot joint
Hinge joint
Condyloid joint
16. Which feature most clearly distinguishes a synovial joint from fibrous and cartilaginous joints?
Dense connective tissue joining the bones without a cavity
A continuous cartilage bridge joining the bones
Complete fusion of the bones by ossification
A fluid-containing joint cavity between the articulating bones
