You have two small triangular scapulas, the bones that connect your shoulders to your arms (humerus). The scapula plays a role in the rotator cuff (anyone out there torn theirs?) and its action is controlled in large part by the trapezius (in the shape of a trapezoid) muscle, which runs from the base of the occipital bone to the spine of the scapula and the lateral third of the clavicle, which is the collar bone and connects the scapula to the sternum, also known as the chest or breastbone running down the center of our chests and where a number of ribs meet. The very nature of this run-on sentence gives you an idea of the run-on connectedness of our bones and muscles!
Getting back to the scapula, Marian Diamond notes it is probably a bone about which most people have never heard until they either break it or take an anatomy class. As Professor Diamond “builds” our musculature, I am continually astounded at the complexity of the muscles – their overlapping and interweaving, criss crossing and intertwining, often massively filling small areas or running long lengths.
I have Louie to help me with the ongoing process of learning and recalling some of the 206 bones of the human body, but have yet to find a Louie-look alike that has muscles on its model!
@brainbits: “I want you to learn to work these out. Then you don’t memorize charts and then you have it–tools–to work with wherever you are.” M. Diamond
@brainbits: Though she teaches about our insides, Marian Diamond exhorts us to move our bodies & experience our muscles to get a sense of how they work.
@brainbits: Marian Diamond goes on to repeat & repeat that the more we know about our bodies, the better care we can take of them. Pays off as we age!
@brainbits: Many muscles meet up at humerus (arm)–Hug yourself–entwine your arms behind–feel your shoulders & pecs–Notice how your back & chest move?
@brainbits: Marian Diamond’s lecture 10 on Human Anatomy is all about Muscles – Popeye would have loved the talk!
@brainbits: Our 206 bones are quite straight forward, esp as compared to our 639 muscles that criss-cross and entwine all over the place!
@brainbits: Busy muscles! They move us–control openings–stabilize joints–maintain posture–produce heat w/exercise–give facial expression–close openings.
