Which is an eccentric function of the lumbricals manus?
A)restrains/slows flexion of fingers two through five at the metacarpophalangeal joint
B)restrains/slows extension of fingers two through five at the metacarpophalangeal joint

Question

Quizplus · Accepted Answer

The lumbricals of the hand play a role in flexing the metacarpophalangeal joints and extending the interphalangeal joints of fingers two through five. Therefore, eccentrically, they would help in controlling or slowing down the extension at the metacarpophalangeal joints, as they work against the extension force.
