Term
| in the sarcomere of the skeletal muscle, myosin is found in: |
|
Definition
|
|
Term
| during crossbridge cycling, tension is created by: |
|
Definition
| change in the shape of the myosin head |
|
|
Term
| according to the sliding filament theory for skeletal muscle contraction, a shortening of the sarcomere is produced by: |
|
Definition
| increase in the amount of overlap b/w the thick and thin filament |
|
|
Term
| maximum tension is produced in a skeletal muscle fiver when it is: |
|
Definition
|
|
Term
| when the muscle is stretched, what happens to the length of the muscle fibers? |

|
Term
| what happens to the length of the sarcomeres when muscle fibers are stretched? |
|
Definition
|
|
Term
| initially, you applied a shock to the shortened muscle and measured the tension. you then stretched the muscle and repeated the experiment. did the amount of tension: |
|
Definition
| increase as the muscle was stretched to about 28mm |
|
|
Term
| if the amount of tension produced by the muscle depends upon the number of crossbridges: |
|
Definition
| increase as the muscle was lengthened to about 28mm |
|
|
Term
| if maximum tension indicates that the thick and thin filaments are set at optimal overlap to produce a maximum number of crossbridges, further stretching of the muscle will: |
|
Definition
| decrease the amount of thick and thin filament overlap |
|
|
Term
| since the tension produced by a contracting muscle fiber depends upon the number of crossbridges b/w the thick and thin filaments, then stretching the muscle beyond 28mm: |
|
Definition
| decreases the amount of overlap and decreases the amount of tension produced by a single contraction |
|
|
Term
| in the intact frog, muscle are held close to their resting length so that maximum tension can be achieved. excessive shortening and lengthening of the muscle is prevented by: |
