Many people tend to make a mistake by calling the shoulder the part of the arm that begins right above elbow. However, it is not very true – this body part should better be called arm. Also other people consider that shoulders actually begin on the back. However, they are not precise and correct as well. In fact if you want to place a shoulder tattoo design, you should look for the body part, where your arm adjoins your body. In this place three bones can be found and every of these three bones are known to represent shoulder. There are also ligaments and ankles.
