Ritz argued that the engrossed copy of the Declaration was signed by Congress on July 4, as Jefferson, Adams, and Franklin had stated, and that it was implausible that all three men had been mistaken.

The seven general types of skeletal muscle. The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm.
As you look at the two muscles it will help to realize that they originate on the border of your scapula (shoulder blade) and insert into your shoulder and upper arm. Insertions always move toward the origination, so this muscle pulls your arm down from a raised position. However, if the muscles are tight, you arenât going to be able to raise your arm. These two muscles ended up being a major part of the pain and debility I experienced when I had frozen shoulder.
