• Articulation that contains a fluid-filled joint cavity between two or more bones

Question 4

Synovial fluid/membrane

Answer 4

provides joint lubrication and nutrition

Question 5

Articular cartilage

Answer 5

• dissipates and absorbs compressive forces

Question 6

Articular capsule

Answer 6

connective tissue that surrounds and binds the joint together

Question 7

Capsular ligaments

Answer 7

• thickened regions of connective tissue that limit excessive joint motion

Question 8

• Blood vessels

Answer 8

provide nutrients to the joint

Question 9

• Sensory nerves
