9. | The term "intrinsic" usually pertains to muscles within or belonging solely to the body part upon which they act. TRUE |

11. | It is not possible for a muscle to cause more than one action in an associated joint. FALSE |
12. | The term "innervation" is used to describe a segment of nervous system and is defined as being responsible for providing a stimulus to muscle fibers within a specific muscle or portion of a muscle. TRUE |
13. | Skeletal muscles are responsible for movement of the body as a whole and movement within each of the joints of the body. TRUE |
14. | The term "extensibility" refers to the ability of a muscle to return to its original length following stretching. FALSE |
15. | All muscle contractions are classified as either isometric or isotonic. TRUE |

17. | Joint movement may occur without any muscle contraction. TRUE |
18. | Eccentric muscle contractions are referred to as muscle actions instead of a contraction since the muscle is shortening as opposed to lengthening. FALSE |

20. | Two different muscles may contract simultaneously at a joint and cause a motion that neither would cause if contracting alone. TRUE |
