On the other hand, if you select the last bone you made and rotate it, only
the one bone will rotate. On the human body, motion generally emanates
from the pelvis area, so the pelvis should be the first joint placed in a model.
The first joint in a hierarchy is called the
root joint
.

Place bones in the spine.
3. You can have more than one bone share the same joint. This is useful when
you are working on attaching other bones to the spine, such as the bones
for the character's arms. In the Front view, hold the cursor over the bone at
the top of the spine just below the neck. You will notice that the cursor will
change. Click on that bone. Your current bone chain now originates with
that bone's joint, as shown in Figure 7.68.
4. Now you can place the bones in the arm by making joints at the shoulder,
elbow, wrist, and base of the fingers, as shown in Figure 7.69.
5. Now you need to position each joint in the other views so it follows the
arm. Start with the shoulder. Move it forward, as shown in Figure 7.70.
