Question 1

joint components

Answer 1

subchondral bone plate
articular cartilage
synovium
joint capsul

Question 2

synovial joint

Answer 2

diarthrodial joint
any joint that allows movement

Question 3

subchondral bone plate

Answer 3

bone just underneath the cartilage

Question 4

articular cartilage

Answer 4

covers bone of joint
provides smooth slippery surface that allows free movement of joint

Question 5

synovium

Answer 5

consists of space (synovial cavity) btw 2 articulating bones
there is a synovial membrane that is the inner lining of this cavity
the synovial membrane secretes synovial fluid that lubricates joint surfaces and removes debris

Question 6

joint (articular) capsule

Answer 6

surrounds joint
unites articulating bones

Question 7

3 phases of bone healing

Answer 7

inflammatory, reparative, remodeling

Question 8

inflam phase of bone healing

Answer 8

hematoma forms at fracture site
provides stability
aseptic inflam occurs
duration: 1-3 days for hematoma; 3 days - 2wk for early repair

Question 9

reparative phase of bone healing

Answer 9

fibrous cartilage: formation of granular tissue containing blood vessels, fibroblasts, osteoblasts
formation of callus: when granular tissue has matured
ossification: space in bone is bridged and fracture ends are united, callus replaced by trabecular bone
duration: 6wks

Question 10

remodeling phase of bone healing

Answer 10

bone consolidation with final remodeling
healing is complete
