Modelling the Arm and preparing for joining joints

Here is the arm modelled.

It's OK. It has the shoulder ready for joining, has a nice elbow that I might tweak better later and wrist ready for making a hand.

But now comes the tricky part.. attaching these parts to the actual body itself.

As you can see from the picture below I am going to have to somehow connect the ends of the legs (and arms respectively) onto the body.

Although the legs, for example, have 12 edges to connect from and the body only has about 6 faces with it's edges to choose from to attach to these 12 edges. It may be that I will have to add a few more divisions on the body or split edges.
