If a muscle crosses the knee joint with a horizontal component to its direction of fibers and attaches onto the tibia at the medial side of the leg,what eccentric function will it most likely have?
A)restrains/slows lateral rotation of the leg at the knee joint
B)restrains/slows medial rotation of the leg at the knee joint
C)restrains/slows flexion of the leg at the knee joint
D)restrains/slows extension of the leg at the knee joint

Muscles that attach to the medial side of the tibia and have a horizontal component are positioned to counteract lateral forces, including lateral rotation. Therefore, their eccentric function would likely involve restraining or slowing lateral rotation of the leg at the knee joint.
