6 types of diarthrosis joints
1. Gliding
2. Hinge
3. Pivot
4. Ball and Socket
5. Saddle
6. Condyloid
What is included in a diarthrodial joint structure?
Bone
Articular Capsule (fibrous membrane and synovial membrane)
synovial fluid/cavity
articular cartilage
no movement in any one plane
nonaxial
movement in one plane
uniaxial
moves in two planes
biaxial
moves in three planes
triaxial
Gliding joints
nonaxial joints that lie next to each other and glide together
ex. intercarpal/intertarsal/facets/sternoclavicular
Hinge joints
uniaxial joints that act like a hinge on a door
ex. elbow, knee
Pivot joints
uniaxial joint of one bone rotating in a ring of another
ex. atlantoaxial joint/ radius/ ulna joint
Ball and Socket joints
triaxial joint where movement is permited in all planes
ex. shoulder, hip
Saddle joints
biaxial joints where opposing bones that come together are convex and concave so the surface of the joints is saddle shaped.
ex. thumb
Condyloid joints
biaxial joint similar to saddle joints except it is a condyle of one bone that fits into an elliptical cavity of another bone.
ex. knuckles/ TMJ
