knee joint
Bone-to-bone connector
ligament
Hinge
limits movements to flexion and extension. e.g. knee, elbow, fingers, and toes
Synovial fluid has two functions:
lubricates and nourishes the cartilage
Pivot
motion is limited to rotation. e.g. neck
Saddle
one articular surface is concave and the other is convex. the two bones fit together. e.g. carpal-metacarpal articulation in the thumb

symphysis
Supination and pronation refer to movement of the ________
wrist and elbow
Saddle joint
thumb
Bursae
1) Closed sacs with a synovial membrane lining 2) Found in spaces of CT between tendons, ligaments and bones. 3) Found wherever friction could develop during movement 4) Three types based on where they are found. . .
according to the degree of movement they allow
Function
