Anatomy
Diarthrosis | Movement |
---|---|
hinge | in one plane about single axis; think hinged door (e.g. elbow, knee, ankle) |
pivot | rotation (e.g. between axis and atlas) |
ball and socket | widest range of all joints (e.g. shoulder joint, hip joint) |
condyloid | in two planes at right angles to each other (e.g. wrist joint between the radius and carpals) |
saddle | same kinds of movements as condyloid joint but freer, think rider in saddle (e.g. thumb, between first metacarpal and carpal) |
gliding | gliding, a nonaxial movement (e.g. between carpal bones; between sacrum and ilium) |
