Joints Review

Which one of these is NOT a structural classification of joints?

• Fibrous

• Cartilaginous

• Synovial

• Diarthrotic

Answer explanation

Diarthrotic is a FUNCTIONAL classification of joints

Which of these functional classifications means that a joint is freely moving?

• Synarthrotic

• Amphiarthrotic

• Diarthrotic

• Synovial

Answer explanation

Synarthrotic - no movement

Amphiarthrotic - slight movement

What is the articular cartilage responsible for in a synovial joint?

• Lubricates and nourishes articular cartilage

• Makes synovial fluid

• Fluid filled potential space (for the joint to move)

• Prevents the crushing of bone ends

What is the joint cavity responsible for?

• Lubricates and nourishes articular cartilage

• Makes synovial fluid

• Fluid filled potential space (for the joint to move)

• Prevents the crushing of bone ends

What is the articular capsule (synovial membrane) responsible for?

• Lubricates and nourishes articular cartilage

• Makes synovial fluid

• Fluid filled potential space (for the joint to move)

• Prevents the crushing of bone ends

What is synovial fluid responsible for?

• Lubricates and nourishes articular cartilage; contains phagocytic cells to remove microbes and debris

• Makes synovial fluid

• Fluid filled potential space (for the joint to move)

• Prevents the crushing of bone ends

There are nerves and blood vessels in joints.

• True

• False

What is a sac lined with a synovial membrane that reduces friction where ligaments, muscles, skin, tendons, or bones rub together?

• Capsule

• Fatty pad

• Bursae

• Articular disc

What is a sac lined with a synovial membrane that reduces friction where ligaments, muscles, skin, tendons, or bones rub together AND completely wrapped around a tendon?

• Tendon sheath

• Bursae

• Fatty pad

• Articular disc

Fibrocartilage that separates articular surfaces to improve "fit" of bone ends, stabilize joint, and reduce wear and tear

• Bursae

• Tendon sheath

• Fatty pad

• Articular disc - menisci
