What will be an ideal response?
Contraction of a flexor muscle produces flexion, which draws a limb in toward the body. Contraction of an extensor muscle moves a limb out from the body (antigravity action). A four-legged animal lifts its paw by contracting the flexors and places the paw back down by contracting the extensors.
