Q

What are the characteristics of synovial joints?

A

Q

Ball and socket joint function

A

allows movement in almost any direction- the greatest amount of joint movement in body

17
Q

Condyloid/ellipsoid joint function

A

similar to ball and socket, but allow lesser degree of movement

18

Saddle joint function

A

similar to ball and socket/saddle, but without rotational movement
