| Question | Answer |
|---|---|
| The muscle that connects to the back of the pelvic girdle and femur | gluteus maximus |
| The way the eye moves during sleep | rapid eye movement |
| This is another name for skeletal muscles, because you can control them by thinking about controlling them | voluntary muscles |
| Muscles that contract and relax without you thinking about them, like cardiac and smooth muscle are called | involuntary muscles |
| Muscles that close the joints | flexor muscles |
| A cellular waste product created when energy is produced anaerobically | lactic acid |
| Muscles that open the joints wider | extensor muscles |
| The type of energy production that requires oxygen | aerobic |
| The tendon that attaches the calf muscle to the heel bone | Achilles tendon |
| The type of cellular energy generation that occurs when there is an inadequate supply of oxygen in that cell | anaerobic |
| A condition that occurs when a muscle is underused and therefore becomes weak and shrinks | atrophy |
| The small strips of protein located inside each myofibril | filaments |
| The muscles that are attached to and move your bones | skeletal muscles |
| The muscle that closes the mouth and keeps it closed | masseter |
| A pair of muscles or muscle groups that act to pull a bone in opposite directions | antagonistic muscles |
| This condition occurs when tendons are overused and become inflamed | tendonitis |
| The muscle type that forms much of the heart | cardiac muscle |
| A sugar that the human body turns certain foods into. It can be used to make energy to power muscle cells | glucose |
| These connect skeletal muscles to bones | tendons |
| The type of action whereby muscles move involuntarily | reflexive |
| This is produced when muscles are partially contracted | muscle tone |
| Strands of protein inside skeletal muscle cells | myofibrils |
| What are the 3 kinds of muscle tissue in your body | skeletal muscles, smooth muscles, and cardiac muscles |
| Which of those muscle kinds are voluntary, and which are involuntary | skeletal muscles are voluntary, smooth and cardiac muscles are involuntary |
| Where is your Achilles tendon | the back of your heel |
| What are antagonistic muscles | muscles that pull your bone in different directions |
| What do muscle cells have a lot of that give them energy | glucose and oxygen ??? |
| What substances help muscles move | blood and nerves ??? |
| What do muscle need to grow | protein |
| How do you keep your cardiac muscle strong | exercise it for 30 minutes, 3 times per week |
| Name 2 places in your body where you find smooth muscles | blood vessels, stomach, bladder, lungs |
| How many times a day does the heart beat? | 100,000 times |
