1. muscles only pull, they don't push
2. muscles contract in the center and pull equally on both ends
3. The action of a muscle on a joint will be determined by the attachments and the path of the muscle
4. Muscles must oppose gravity to produce a movement or maintain a position
6. three types of contractions are possible- shortening, static, lengthening |
