5
Q
Ball & Socket?
A
MULTIAXIAL- shoulder and hip joints
-smooth, allows for easy movement
6
Q
Ellipsoid?
A
BIAXIAL- wrist
- smaller ball and socket
- egg shaped
- can only rock back and forth in 2 directions
7
Q
Saddle?
A
BIAXIAL- base of thumb joint
- think of a rider on a horse
- allows for movement in 2 planes (rocking back and forth)
8
Q

UNIAXIAL- neck/head rotation
-only rotation possible around one axis
9
Q
Hinge?
A
UNIAXIAL- elbow joint
- movements are limited to flexion & extension
- like a hinge of a door
10
