NSCA-CSCS Exam Chapter 1 Practice

Questions and Answers 100% Pass


To what structures do the cross-bridges attach during muscle action? - ANSWER✔✔-Actin


Which substance regulates muscle actions? - ANSWER✔✔-Calcium


Which substance acts at the neuromuscular junction to excite the muscle fibers of a motor unit? -

ANSWER✔✔-Acetylcholine


Which muscle fiber type is the MOST beneficial for a marathon runner? - ANSWER✔✔-Type I


When throwing a baseball, an athlete's arm is rapidly stretched just prior to throwing the ball. Which of

the following structures detects and responds to that stretch by reflexively increasing muscle activity? -

ANSWER✔✔-Muscle Spindle


From what is the heart's electrical impulse normally initiated? - ANSWER✔✔-SA Node


Which of the following occurs during the QRS complex of a typical ECG? - ANSWER✔✔-repolarization of

the atrium and depolarization of the ventricle.


A-Band - ANSWER✔✔-overlapping actin and myosin


acetylcholine - ANSWER✔✔-Arrival of the action potential at the nerve terminal causes release of a

neurotransmitter, ______, which diffuses across the neuromuscular junction. Once a sufficient amount is

released, an action potential is generated across the sarcolemma, and the (muscle)fiber contracts.


Actin and Myosin - ANSWER✔✔-contractile proteins in muscle

Action potential - ANSWER✔✔-the change in electrical potential associated with the passage of an

impulse along the membrane of a muscle cell or nerve cell.


All-or-none Principle - ANSWER✔✔-the strength by which a nerve or muscle fiber responds to a stimulus

is independent of the strength of the stimulus. If the stimulus exceeds the threshold potential, the nerve

or muscle fiber will give a complete response; otherwise, there is no response.


Alveolar Pressure - ANSWER✔✔-the pressure in centimeters of water pressure (cmH2O) held within the

alveoli of the lungs during inspiration. The pressure value is the difference from atmospheric pressure,

which is considered zero when establishing the value.


Alveoli - ANSWER✔✔-where gases are exchanged in respiration.


Aortic Valve - ANSWER✔✔-prevents backflow from the aorta into the ventricles during ventricular

relaxation (diastole)


Arterial System - ANSWER✔✔-Carries blood away from the heart


Arteriole - ANSWER✔✔-small branches of arteries that act as control vessels through which blood enters

the capillaries.Play a major role in the regulation of blood flow to the extremeities.


Artery - ANSWER✔✔-Their function is to rapidly transport blood pumped from the heart.


Atrioventricular (AV) Bundle - ANSWER✔✔-conducts the electrical impulse to the ventricles


Atrioventricular (AV) Node - ANSWER✔✔-electrical impulses coming from the SA node are delayed

slightly here before passing into the ventricles


Atrioventricular (AV) Valves - ANSWER✔✔-consists of the tricuspid and mitral valve and prevent the flow

of blood from the ventricles back into the atria during ventricular contraction (systole).
