Synovial Joints

Ball and Socket

Smooth Hemospherical head fits in a cuplike Socket
ie. head of humerous in glenois fossa
Multiaxial Joint

Condyloid(Ellipsoid) Joint

Oval Convex Surface on one bone fits into a simularly shaped depression on the next
Radiocarpal Joint
metacarpophalange join
Biaxial Rotation

Saddle Joint

Each articular surface is shaped like a saddle , concave i one direction and convex on the other.
Trapeziometacarpal joint at the base of thumb
Biaxial Joint
More moveable than condyle or hinge, forms primate oposable thumb

Gliding Joint

Flat articular surface in which bones slide over eachother
non axial join
considered amphiarthrosis

Hinge Joints

One bone with convex surface that fits into a concave depression on the other bone
looks like a hinge
ulna and humerous
femus and tibia
monoaxial

Pivot Joint

One bone has a projection that fits into a ringlike ligaments of another
First bone rotatoes on its longitudinal axis relative to the other(monoaxial)
atlantoaxial joints(dens and atlas)
proximal radoulnar noint allows the radius to rotate during pronation and upination.
