Scapula Rotation during Arm Elevation

I came across this information on exactly how and around where the scapula rotates during arm elevation.

link

Interesting point of anatomy how the center of rotation moves to a second location. Might be of interest to 3D riggers, as well as figure artists.

Cool. Thanks for the link jfrancis.

Have always found the scapular movement to be a tricky one. Often surprised at how much it really does move around under the skin. It's an important bony landmark, but one that, well, moves around quite a bit.

Would have been nice to see more diagrams etc. Muscles affecting the scapular and relationship to rig cage for example. Never mind, still a lot more detailed than most.

Thanks again.

Wow! Those X-Ray Fluoroscopy videos are great.

You can even see the heart beating in real time.

Thanks.

Interesting tidbits, Joseph.

If you are interested in the Scapulothoracic joint, the range of motion of the shoulder girdle and joint, and all of the muscles associated, you may be interested in this 541 page musculoskeletal atlas (dubbed one of the best out there, if not the best):
Thieme Atlas of Anatomy
I’m blown away by the quality of the illustrations (though the art looks a bit washed out in the preview shown) and extensive info. Frank Netter (gold standard medical illustrator) will have to take a back seat to the level of art here.

Problem—if you want to see the head, well that’s in another of the 3 part text set.
Thieme Atlas of Anatomy: Head and Neuroanatomy

Thanks a lot for that book reference, Bill!

Does the book include range of motion descriptions in degrees for all joints and ie in case of the shoulder at what range other joints take over to conclude a certain motion etc?

Cheers!

There are detailed diagrams with degrees and axis of rotation of everything jointed, from the scapula to the foot, hands, fingers and toes. It doesn’t present chains of joint movements like in a running cycle, just what applies to the particular joint. This and the companion books are great reference sources. The only drawback is the musculoskeletal atlas does not include the head. You’ll have to buy the companion text 'Atlas of Anatomy: Head and Neuroanatomy' for that, if interested.

Thanks a lot for that info!

Weird, looking at Amazon-Germany, I found that the german original is quite a bit more expensive then the english translation.

Cheers!
