Which types of Muscle tissue can be Consciously controlled? Which cannot be consciously controlled? How does the appearance of smooth muscle differ from that of cardiac or skeletal muscle? What are the general functions of muscle tissue? What properties do all muscle tissues have in common? Which property do muscle tissues and neurons share?
What functions does fascia serve? What is the structural difference between a tendon and an aponeurosis? What are the functions of T tubules? Myoglobin? Sarcoplasmic Reticulum? Which are all unique to muscle fibers?
Which portion of the sarcolemma contains acetylcholine receptors? Describe the steps that occur for an impulse arriving at the synaptic end build to result in a muscle action potential: What happens to acetylcholine once it has bound to its receptor? What happens to the distance between neighboring Z Discs when thin filaments in a sarcomere slide toward the M Line?
When Thin Filaments slide away from the M line? As each Myosin head detaches from a thin filament, what stops the thin filament from sliding back to its original, relaxed position? How does sarcomere shortening result in shortening of an entire muscle and movement of a bone? How does a skeletal muscle fiber relax? What are the three functions of ATP in muscle contraction and relaxation?
What is the difference between unfused tetanus and fused tetanus? Which type of stimulation can allow you to lift a heavier object? In what ways does motor unit recruitment assist in muscle function? Which molecule is the only direct source of contraction energy for a muscle fiber? Which ATP-producing reactions provide ATP during a 1000-meter run? Which occur within Mitochondria?
What is Muscle Fatigue? Of the three types of Muscle tissue, which have contractile proteins organized into sarcomeres? Which contain Transverse Tubules? Which contain Intermediate Filaments? Which contain Dense bodies?
How do the speed and duration of contraction in a smooth muscle fiber compare with those in a skeletal muscle fiber?
