NSCA – CPT UPDATED ACTUAL
Questions with CORRECT Answers
Epimysium - CORRECT ANSWER - a sheath of fibrous connective tissue surrounding the
muscle that is continues with tendons at the end of a muscle


Tendon - CORRECT ANSWER - a special connective tissue that is attached to the bone
periosteum; any contraction of the muscle pulls on the tendon and, in turn, the bone.


Muscle fibers - CORRECT ANSWER - long muscle cells that create mucles



Fasciculi - CORRECT ANSWER - bundles or muscle fibers grouped under the epimysium



Periosteum - CORRECT ANSWER - Tissue that surrounds the fasciculi as a whole and
lies beneath the Epimysium


Endomysium - CORRECT ANSWER - Tissue that surround each individual muscle fiber



Sarcolemma - CORRECT ANSWER - Tissue that envelops muscle fibers



Myofibril - CORRECT ANSWER - long tissue threads that contains the apparatus the
contracts the muscle cells (found in striated muscles)


Myofilaments - CORRECT ANSWER - filaments of myofibrils constructed from protein,
two types are myosin and actin


cross-bridges - CORRECT ANSWER - the globular head of a myosin molecule that
projects from a myosin filament in muscle and in the sliding filament hypothesis of muscle
contraction is held to attach temporarily to an adjacent actin filament and draw it into the A band
of a sarcomere between the myosin filaments

, Sarcomere structure - CORRECT ANSWER -



Sliding filament model - CORRECT ANSWER -



Electrocardiogram (ECG) - CORRECT ANSWER -



Type I muscle fiber - CORRECT ANSWER - Slow twitch, fatigue resistant, high capacity
for aerobic energy supply but have limited potential for rapid force development (low aerobic
power & low actomysin myofibril ATPase activity).


i.e postural muscles like neck and spine


Type II muscle fiber - CORRECT ANSWER - Fast twitch, inefficient & fatiguable, low
aerobic power, rapid force development, high actomysin myofibril ATPase activity, and high
anaerobic power


Type IIa and Type IIx muscle fiber difference - CORRECT ANSWER - Type IIa fibers
have greater capacity for aerobic metabolism and more capillaries surrounding them, therefore
have greater resistance to fatigue


P wave - CORRECT ANSWER - depolarization of the atria in response to sinoatrial (SA)
node triggering, thus resulting in atrial contraction


QRS complex - CORRECT ANSWER - Depolarization of ventricles that triggers
ventricular contraction, atrial repolarization occurs as well


T wave - CORRECT ANSWER - Ventricular repolarization
