|---|---|
| voluntary muscle | skeletal |

| f the leg is moved out to the side away from the body, the movement is ____. | abduction |
| If the lower leg is straightened away from the upper leg, the movement is ____. | extension |
| The muscle on the upper back and neck that extends the head and moves the shoulder is the | trapezius |
| The muscle on the upper arm that extends the lower arm is the ____. | triceps brachii |
| The muscle on the upper chest that adducts and flexes the upper arm is the ____. | pectoralis major |
| The muscle on the front of the thigh that extends the leg is the ____. | quadriceps femoris |
| The muscle that extends from the ribs to the pubis and compresses the abdomen is the ____. | rectus abdominus |
| The muscle on the front of the lower leg that flexes and inverts the foot is the ____. | tibialis anterior |
| The muscle on the buttocks that extends the thigh is the ____. | gluteus maximus |
| A group of inherited diseases that lead to chronic, progressive muscle atrophy is ____. | muscular dystrophy |
| State of partial contraction | Muscle tone |
| The end of a muscle that moves when the muscle contracts | Insertion |
| Severe tightening of a flexor muscle | Contracture |
| Control over the action of a muscle | Voluntary |
| Ability of a muscle to be stretched | Extensibility |
| Ability of a muscle to respond to a stimulus | Excitability |
| Ability of a muscle to return to its original shape | Elasticity |
| Strong, tough, connective-tissue cord that attaches muscles to bones | Tendon |
| Moving a body part toward the midline | Adduction |
| Bending the lower arm up toward the upper arm | Flexion |
| Moving in a circle at a joint | Circumduction |
| Increasing the angle between two bones | Extension |
| Turning the head from side to side | Rotation |
| Moving the arm out to the side | Abduction |
| three main types of muscle | cardiac, visceral, skeletal |
| contracts to circulate blood | cardic muscle |
| contracts to cause movement in the internal organs of the body | visceral/smooth muscle |
| attaches to bones and causes body movement | skeletal muscle |
| treatment for muscle spasms or cramps | gentle pressure and stretching of the muscle |
| treatments for a strain. | rest, muscle relaxants or pain medications, elevating the extremity, alternating hot and cold applications |
| treatments for fibromyalgia. | physical therapy, massage, exercise, stress reduction, medication to relax muscles and relieve pain |
| function of skeletal muscles | attach to bones to provide voluntary movement, produce heat and energy for the body, help maintain posture, protect internal organs |
| Muscles are bundles of muscle fibers held together by | connective tissue. |
| When a muscle attaches to a bone, the end that does not move is called | the origin |
| When muscles are not in use they are | partially contracted |

| a group of inherited diseases, that lead to chronic, progressive muscle atrophy | Muscular dystrophy |
| When muscles are not used for a long period of time, they can ____ | atrophy |
| myalgia | muscle pain |
| a overstretching of or injury to a muscle and/or tendon | strain |
