Wrist Locks:

Next to the fingers, the wrist joint is one of the weakest joints in the body.  The wrist can be twisted to the inside and to the outside. The wrist can be bent to toward the elbow with the palm in or out.  Along with these four basic movements, the wrist can be twisted while it is bent; which increases the available techniques.

Wrist techniques are an important part of self-defense. There are many schools of martial arts that use the wrist  in a majority of their techniques.
