Shoulder 1 & 2 Constructions

Shoulder 1 & 2 Constructions


Okay, you probably can’t see me, but I have
the camera zoomed in to take a close look at the muscles we’ll be constructing. Um, here deep to the pec major, which you
have not put on yet, is the pec minor, going from upper ribs to the corocoid process of
the scapula. And then really important is the serratusa
anterior. This muscle runs from anterior and lateral
ribs, all the way around the rib cage to the vertebral border of the scapula. You have instructions on how to make the scapula
more mobile, so you can get to this point – but here is the scapula from the front
view, and this muscle runs all the way to its farthest-away border – the vertebral
border. Um, on the back, we’ll be looking at the
three parts of the trapezius, the upper and lower – which are both involved in upward
rotation of the scapula, and the middle, which is more involved in retraction of the scapula. So whenever I do something passively, the
muscle that should be involved in that motion should get more slack in it. And when I push the opposite way, that muscle
should be stretched. So the three parts of the trapezius, and then
rhomboid major and minor which here are shown as one muscle together because functionally
they work together. Um, back to the serratus – just to see a
good picture – serratus is involved in pushing the scapula forward into protraction. So, this movement here – and you’ll be
working with a scapula that is this free to move around so you’ll be able to get to
that vertebral border, if you follow the directions on how to free the scapula from the rib cage.
