6 types of diarthrosis joints
4. Ball and Socket
What is included in a diarthrodial joint structure?
Articular Capsule (fibrous membrane and synovial membrane)
no movement in any one plane
movement in one plane
moves in two planes
moves in three planes
nonaxial joints that lie next to each other and glide together
uniaxial joints that act like a hinge on a door
ex. elbow, knee
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
biaxial joints where opposing bones that come together are convex and concave so the surface of the joints is saddle shaped.
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
