freely movable joint exhibiting a joint cavity enclosed by a fibrous capsule lined with synovial membrane

Answer 3

synovial joint

Question 4

hyaline cartilage covering the epiphysis of a bone at a joint

Answer 4

articular cartilage

Question 5

the joint surfaces are enclosed by a sleeve, or layer, or fibrous connective tissue, which is lined with a smooth synovial membrane

Answer 5

articular capsule

Question 6

enclosed by articular cartilage; contains lubricating synovial fluid secreted by the synovial membrane

Answer 6

when a bone is forced out of its normal position in the joint cavity

Answer 9

dislocation

Question 10

restoring broken bone ends ( or dislocated bone) to its original position

Answer 10

reduction

Answer 14

condylar joint

Question 15

biaxial synovial joint in which both articulating bones have both convex and concave surfaces

Answer 15

saddle joint

Question 16

multiaxial synovial joint in which the rounded head of one bone fits into a socket (depression) of the other

Answer 16

when the ligaments or tendons reinforcing a joint are damaged by exercise, or are torn away from the bone

Answer 18

sprain

Question 19

inflammation of the joints
