Guuueeessss what time it is?!
ITS ANATOMY TUTORIAL TIIIIMEEEE!
And by that I mean I hope to convey some of the junk that should help in Anatomy with the upper body.
Men and women have similar muscles, but ladies are definately built differently, therefore this is more geared to MALE muscles.
1. We have Mr. Skeleton. If he could smile he would while he waves.
The point in me drawing a skeleton first is to illustrate what the skeleton should look like in proportion to itself as a starting point.
That isn't to say that you should start every drawing as a skeleton! Just be aware of the proportion of the skeleton, the space between relative objects. Such as the Elbow and the Hip, the space between the Ribs and the Pelvis, and almost more importantly, the connection of the clavicle (Collar bone) to the rib cage AND to the Scapula (Shoulder Blades).
Another thing to pay attention to that some people don't quite grasp is that the FOREARM is two bones! Not only are they two bones, but as you rotate your hand, the bottom of those bones follow their anchor point on your hand. Try it out! Grip your wrist firmly with your fingertips and feel the bones stay put! They are at a precise angle to allow a certain range of movement for you!
Which reminds me, all the bones in your body are there because muscles and tissues connect to them! Larger areas or ends that on a skeleton don't seem like they do much of anything are there for either joints or muscles to better connect to. Your HIPS are a good example of that.
2. Mr. Skeleton has some Muscles! Well the outlines of them anyways.
The point of this illustration is to show you where muscles should be in proportion to the skeleton, and where the muscles connect.
As I said, all muscles have to connect to something. Larger muscles especially need a skeletal anchor point (which is illustrated in step 4 with blue lines).
This illustration is sorta meant to show you not only where stuff SHOULD be, but to show you how they stretch with a little movement.
The shoulder muscle is a hard one to grasp, but it basically is anchored at it's top-most part to the Collar Bone (clavicle), and when you raise your arm the clavicle moves, but the shoulder mucle works harder to raise your arm, flexes, and visually pops upwards from the collar bone anchor point.
Although it's not pictured here very well, the Shoulder Blade (Scapula) also moves with the arm. You can tell more from the skeleton what there is connect to each other, but if you move the arm, so do you move the Collar Bone and Shoulder Blade. That's why in men more visibly a muscle from the back seems to connect from the edge of the shoulder muscle to the back. The Shoulder Blade has a DEEP ridge in it's upper part at a diagonal made SOLELY for big muscles to latch on to! Check it out, google Skeletal Anatomy and look at a back piece!
3. Mr. Skeleton no more! Now we have Mr. MUSCLES!
Here is just a more clear definition of muscles in proportion to one another. Each line is a clear separation of different muscles (not all of them obviously, but some major muscle groups), and how they should look in when more relaxed, flexing or rotating (as by the raised arm).
A good thing to mention here is that there are two much larger muscles on either side of the Neck to which are present visibly in anyone unless they are a... huskier fellow/lass (pun intended). These muscles start at the starting point of each respective side of the clavicle and attach below a human being's ear. They are there moreso for rotation, but they also protect the most major vessels into the head (Juggular), which are on the inside. Half way up from the neck is the Adams Apple btw.
4. Anchors and Bones!
When everything is assembled you should know that some muscles work with each other, and that some bones don't have/need any muscle above them.
Yellow areas here are bones that have a layer of fat/skin over them, but no muscle.
Blue areas here are anchor points.
Notice something? Anchor points are almost always touching bones!
This is to illustrate that your body moves by different muscles contracting and extending.
Your bicep, for example, contracts when you bend your arm in, and extends when you extend your arm.
I'd just like to mention here that when you bend forward, because the anchor of your abdominal muscles tend only at the rib cage and Pelvis, that they harden to a near flat. That means that instead of your body bending like a piece of paper, that your abs stay straight as your body bends.
*Bonus:
Hopefully you can see my crappily illustrated Cartilage of the Rib Cage. Bones are SOLID, but Cartilage moves around while keeping a constant area without stretch. This explains how you can breath and your chest can rise/fall without trouble.
Also notice the back of the Pelvis is way higher than the front. That's cuz your back needs less area to get the most power out of your back muscles.
The little eye sockets at the bottom of the butt? Those are connection points for your butt. Legit.
Your hands have bones connecting to your wrist as though it were another part of the digit. They ARE NOT where you see those little bumps on top of your hand (well yes where your knuckles are). The thin strand that pops up when you extend your fingers is a SINEW, a much tougher than muscle fiber meant to optimize the strength in your hand.
Kay that's all the smarts I can vomit out atm, hope that helps a little!
