4. Joint classification
manner or type of material by which bones articulate
relates to movement
Fibrous or cartilaginous
synovial

5. Fibrous
bound by collagen
fibers
little or no movement
Cartilaginous
linked by cartilage
some movement

6. Examples of fibrous joints in the skull

8. Synovial joints
freely moveable
articulating bones covered with
hyaline cartilage
bones separated by joint cavity
joint cavity contains synovial fluid
joint is enclosed by joint capsule

Joint (articular) capsule
(Synovial membrane + fibrous capsule)
Joint cavity
(contains synovial fluid)
Synovial fluid and warming up

11. sac filled with synovial fluid and bones
Bursa
sac filled with synovial fluid
between muscles or tendons
and bones
for protection and sliding
bursitis - inflammation
Tendon Sheaths
elongated bursae
wrap around a tendon
for protection and sliding
tenosynovitis
tendonitis
