Arms

It is the flexibility of our arms and hands that makes us unique among the many species of the world.  Therefore, it is important to know how to draw them.  For the limbs, male appendages will be used for examples, since the muscles are more defined.  Female arms and legs tend to be smoother.  When the arm is lowered, it is more relaxed, so the muscles are loose and are not as visible.  Still, the deltoids, or shoulder muscles should be fairly visible as a round hump on the top of the arm, as can be seen in the picture on the far left. The upper arm becomes thinner since the biceps and triceps are fairly relaxed.  The arm flares out again at the elbow, where the forearm muscles are joined to the bone, and then tapers off again to form the wrist.  When the arm is raised up in a fist, however, tension can be seen all along the arm, as can be seen in the center picture.  The tendons in the wrist protrude and the muscles on the inside of the arm bunch up around the elbow.  The biceps bulge upwards and the triceps are stretched out on the bottom.  The deltoid overlaps the biceps and bunches upwards as well, and the muscle extends down to the chest area.  When the arm is down turned at a 90 degree angle, it is almost the same as the raised arm, except that the biceps are now facing downwards, since the elbow is in the same position.  Since the forearm is pointing down, the muscles in the forearm are more relaxed.&
