muscular system | bundles of muscle fibers held together by tissues |
excitability | irritability,the ability to respond to a stimulus such as nerve impulse |
contractibility? | muscle fibers that are stimulated by nerves contract, or become short and thck, which causes movement. |
extensibility | the ability to be stretched |
elasticity | allows the muscle to return to its original shape after it has contracted or stretched |
cardiac muscle | forms the walls of the heart and contracts to circulate blood |
visceral (smooth muscle) | found in the internal organs of the body such as those of the digestive and respiratory system, and the blood vessels and eyes |

skeletal muscle | attached to the bones and causes body movement |
voluntary | person has control over its action |
Tendons | Strong, tough connective tissue cords |
Fascia | a tough,sheet like membrane that covers and protects the tissues |
origin | a muscle attaches to a bone,the end that does not move is called the origin |
insertion | the end that moves when the muscle contracts is called the insertion |
Adduction | Movement of a limb toward the midline of the body |
abduction | the movement of a limb away from the midline of the body. |
