If a muscle crosses the spinal joints of the trunk laterally with a vertical direction to its fibers,what eccentric function will it most likely have?
A)restrains/slows flexion of the trunk at the spinal joints
B)restrains/slows same-side (ipsilateral)lateral flexion of the trunk at the spinal joints
C)restrains/slows opposite-side (contralateral)lateral flexion of the trunk at the spinal joints
D)restrains/slows contralateral rotation of the trunk at the spinal joints

If a muscle crosses the spinal joints of the trunk laterally with a vertical direction to its fibers, it is most likely an oblique muscle. The oblique muscles are oriented in a diagonal or oblique direction and are responsible for lateral flexion and rotation of the trunk. If the muscle is crossing the spine vertically, it means it is restricting the lateral movement of the spine, which would restrain/slows opposite-side (contralateral)lateral flexion of the trunk at the spinal joints.
