Hi,
I'm working in a new conversion, which I will soon unveil - working in this particular projects, I found a fairly common anatomical anomaly: the incorrect relationship betwen a raised arm and its shoulder. We call this "The Action Man Syndrome" in our modelling association. I believe this matter merits being treated separately, hence this posting.
A human arm is NOT connected to the rib cage by means of a ball and socket joint, like that of an articulated doll (as those used in Arts, or an Action Man). Without going into too much detail, an arm is attached to the scapula, which is linked to the clavicle. When you raise an arm these bones are raised too, as is all the muscular mass around them, and the more you raise the arm, the more the shoulder rises too.
You can see this graphically here:
In fact, a lot of modellers, when converting a pose or scratchbuilding, and even not a few commercial sculptors, do not pay attention to this feature, and the result is a odd-loking (and anatomically impossible) appearance:
In some cases, surely, this may be attributed to the use of dolls as models, or academic figures as a basis on which to model an original figure - these have the movement limitations I have mentioned.
These drawings come from an old Military Modelling by C. Buchanan.
