Skeletal Muscle

5. Rapid loss of muscle commonly associated with cancer.
7. Muscles that work to increase joint angle.
8. This type of contraction occurs when the muscle force is greater than the resistance.
10. neurotransmitter released from the motor neuron
11. These "properties" include oxidative capacity, myosin ATPase isoform, and number of contractile proteins.
12. Defined as a decline in muscle power output.
13. Muscle cell membrane.
15. These ions compete with calcium binding to troponin.
16. Thick filament.
17. Surrounds bundles of muscle fibers.
18. Muscle loss related to age.

1. Muscles that work to decrease joint angle.
2. When the frequency of stimulation is the highest.
3. Contain contractile proteins.
4. These cells play an important role in muscle growth and repair.
6. Depletion of the storage form of this macronutrient can contribute to fatigue.
9. Functional unit of muscle.
14. Skeletal muscles help with breathing and _______.
19. Thin filament.
20. Binds to troponin and causes a position change of tropomyosin.
