3 Joint in which two bones are separated by a space called a joint cavity Most are freely movable

4 Articular capsule Synovial membrane and fluid Articular cartilage Articular discs and menisci Tendon Ligament Fatty pad Bursae

5

6 continuous with the periosteum of articulating bones and unites the articulating bones; consists of two layers – the outer fibrous membrane that may contain ligaments the inner synovial membranesynovial membrane highly innervated, but avascular

7 7 Articular cartilage covers the ends of bones. It has a smooth, slippery surface, which allows the bones to slide over each other without rubbing.

8

9 It is the partition found between capsule and the joint cavity.

10 Lubricating fluid in joint cavity to reduce friction

11 thin, oval plate, placed between the condyle of the mandible and mandibular fossa

12 Fibrous bands or sheets of connective tissue linking two or more bones or cartilages together. One or more ligaments provide stability to a joint during rest and movement.

13 tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension.

14 the fluid sacs and synovial pockets that surround and sometimes communicate with the joint cavity.

17 17 Plane joint Hinge joint Pivot joint Condyloid joint Ellipsoid joint Saddle joint Ball and socket joint

18 a synovial joint in which the opposed surfaces are flat or only slightly curved.

20 Resemble door hinge Flexion and extension possible

21 Central bony pivot surrounded by bony ligamentous ring Rotation is only possible movement

22 Oval convex surfaces on one bone fits into a concave shaped depressions on the next

23 Elliptical convex surface fits into elliptical concave surface Flexion, extension, abduction and adduction occur Rotation is not possible

24 Articular surfaces resemble a saddle on a horse back Flexion, extension, abduction, adduction and rotation are permitted

25 Most mobile joints of the body All movements possible
