Write True or False: Fascia is a sheet or band of irregular connective tissue.
(a)
The motor end plate differs from the rest of the sarcolemma in that it contains large numbers of ________.
calcium
synaptic vesicles
ATP
acetylcholine receptors
Thick filaments differ from thin filaments in that thin filaments possess:
a titin binding site located on the myosin head.
an actin binding site located on the myosin head.
thin filaments contain actin and thick filaments contain myosin.
thin filaments are composed of z discs and troponin.
Which of the following will increase muscle tension?
Decreasing sarcomere length so that the actin and myosin completely overlap from one end to end.
Adjusting sarcomere length so that the actin and myosin partially overlap.
Increasing sarcomere length so that the actin and myosin do not touch.
None of the above, muscle tension is always constant, so there no way to increase it.

creatine phosphate.
amino acid breakdown.
aerobic respiration.
anaerobic respiration.
Write True or False: Muscle tone keeps muscles firm but does not produce enough force to cause movement.
(a)
Which of the following statements is INCORRECT?
Concentric isotonic contractions result in muscle shortening.
In isometric contractions, the tension generated is not great enough to move the load
Eccentric isotonic contractions result in controlled lengthening of the muscle.
