| External oblique | Lateral anterior abdominal |
| Extensibility | ability to be stretched |
| Elasticity | allows muscle to return to its original shape |
| Cardiac Muscle | Forms walls of heart,Contract to circulate,Involuntary muscle |
| Visceral or Smooth | Contract to cause movement,found in internal body organs,Contract to cause movement,Digestive, respiratory, blood vessels, eyes |
| Skeletal Muscle | Attached to bones,Causes body to move,need rest |
| Adduction | Moving a body part toward the midline |
| Abduction | Moving a body part away from the midline |
| Flexion | Decreasing the angle between two bones, or bending a body part |
| Extension | Increasing the angle between two bones, or straightening a body part |
| Rotation | Turning a body part around its own axis; for example, turning the head from side to side |
| Circumduction | Moving in a circle at a joint, or moving one end of a body part in a circle while the other end remains stationary, such as swinging arm in a circle |
| Pronation | Turning a body part downward; turning “palm down” |
| Supination | Turning a body part upward; turning “palm up” |
| Functions of muscles | Attach to bones to provide voluntary movement,Produce heat and energy, Help maintain posture, Protect internal organs |
| Tendon | strong, tough connective tissue cord |
| ORIGIN | end that does not move |
| INSERTION | end that moves when muscles contracts |
| ATROPHY | wasting away- occurs when muscles are not used for long periods of time |
| CONTRACTURE | severe tightening of a flexor muscle, permanent contraction |
| Agonist | initiates movement |
| Antagonist | reverses or opposes a particular movement |
| Superficial muscle | closest to skin |
| Deep muscle | closer to internal organs |
