HES 202 - Muscular System Exam Questions
and Answers with Verified Solutions | Latest
Updated 2026
Concentric isotonic exceeds load, sarcomeres shorten
Eccentric isotonic doesn't exceed load, sarcomeres lengthen
Isometric contraction actin myosin cross bridges doesn't exceed
load, no
movement
submaximal isometric agonist and antagonist muscles both
contract to
maintain joint position, therefore no
movement
Synergist Muscle that aids a prime mover in a
movement and
helps prevent rotation
muscle contraction Interactions between actin and myosin
filaments of
the sarcomere are responsible for
fatigue occurs due to decrease in force production at cross
bridges, and
contraction speed
