NASM-CPT Muscular System
During the squat, the gluteus maximus serves as what kind of muscle? - ANSagonist
ANSActin is the short, string-like filaments that cause muscle contraction. Which of the
following best describes the function of agonist muscles? ANSType IIx muscle fibers fatigue
more quickly than type IIa muscle fibers. What is one difference between type IIa and type
Iix muscle fibers? What is the communication link between the nervous system and the
muscular system known as? - ANSNeural activation.
ANSEndomysium is the name of the deepest layer of connective tissue. ANSEpimysium is
the connective tissue layer that lies beneath the fascia that surrounds the muscle. What is
the main idea of the "All or Nothing" law? - ANSMotor units either contract maximally or not
at all.
ANS The connective tissue that surrounds fascicles is the perimysium. What is the role of
stabilizer muscles during movement? - ANSSupporting the prime mover and synergist
ANS explains how thick and thin filaments slide past one another in the sliding filament
theory. What is the thick filament that produces muscular contraction? - ANSMyosin.
ANSTransmit electrical impulses from the nerve to the muscle is the most accurate
description of their function. What most closely describes tendons? - ANSAttach muscles to
bone and enable muscles to produce force.
What role does the sarcomere play for the muscular system? - ANSProduces muscular
contraction.
What function does the psoas perform during a squat? - ANSantagonist What kind of
muscles help primary movers move? - ANSSynergist Which characteristics describe type I
(slow-twitch) muscle fibers? - ANSSmaller in size, increased oxygen delivery, less force
produced.
What characteristics are associated with type II (fast-twitch) muscle fibers? - ANSLarger in
size, decreased oxygen delivery, and increased force produced When performing the
overhead press, which muscle acts as the agonist? - ANSDeltoid Which muscle functions as
the antagonist during the overhead press? - ANSLatissimus dorsi
Which muscle functions as the stabilizer during the overhead press? - ANSRotator cuff
When performing a squat, which muscle acts as the stabilizer? - ANS, or transversus
abdominis During the overhead press, which muscle acts as the synergist? - ANSTriceps
The agonist for the chest press is which muscle? - ANSPectoralis major During the chest
press, which muscle acts as the antagonist? - ANSPosterior deltoid The stabilizer for the
chest press is which muscle? - ANSRotator cuff The anterior deltoid muscle is the synergist
for the chest press. Which type of muscle opposes the dominant force? - ANSAntagonist
When performing a squat, which muscle is considered to be the synergist? - The
ANShamstring complex
