Question
A triphasic burst pattern on an EMG characterizes muscle trios labeled with this term, which enable quick and powerful ballistic movements while preventing injuries caused by overextension. For 10 points each:
[10m] Give this term that describes muscle pairs like the biceps and triceps. In these pairs, one muscle works against a “prime mover,” as seen when the latter flexes and the former extends.
ANSWER: antagonistic pairs [or agonist-antagonist pairs]
[10e] Though they’re normally antagonists, these muscle groups work synergistically when standing up in Lombard’s paradox. These muscles comprise the thigh’s posterior and anterior compartments. Name either.
ANSWER: hamstrings OR quadriceps [accept hammies in place of “hamstrings”; accept quadriceps extensor or quads in place of “quadriceps”; prompt on semimembranosus or semitendinosus or or biceps femoris; prompt on rectus femoris or vastus lateralis or vastus intermedius or vastus medialis]
[10h] During a bicep curl, the deltoid acts as this type of synergist, which focuses on stabilizing the origin of the prime mover.
ANSWER: fixator
