Question 17

why the gluteal medius and maximus is essential

Answer 17

maintaining the
trunk upright when the foot of the
opposite side is raised from the ground in
walking or running. The body weight
tends to make the pelvis drops
downwards on the unsupported side.
Gluteus medius and minimus on the
supporting side raise the opposite side of
pelvis, allowing the raised limb to be
