Which is an eccentric function of the transversospinalis group?
A)restrains/slows extension of the arm at the glenohumeral joint
B)restrains/slows elevation of the scapula at the scapulocostal joint
C)restrains/slows contralateral rotation of the trunk at the spinal joints
D)restrains/slows ipsilateral rotation of the trunk at the spinal joints

Question

Quizplus · Accepted Answer

The transversospinalis group includes several muscles that are involved in rotation and stabilization of the spine. The function of an eccentric contraction is to resist or slow down a movement. The only option that describes a movement that is resisted or slowed down by an eccentric contraction of the transversospinalis group is ipsilateral rotation of the trunk at the spinal joints. Therefore, the correct choice is D.
