The main role of fixator muscles in the human body is to stabilize joints and maintain the body's posture during movement. Fixator muscles work synergistically with other muscles to provide stability and support for efficient movement. They help in preventing unwanted movement of joints and assist in maintaining proper alignment during physical activities.

Yes, and knee extension would be when the knee is straight.
The knee. The prime mover for extension of the knee joint is the quadraceps femoris which is actually a group of muscles consisting of rectus femoris, vastus lateralis, vastus medialis and vastus intermedialis. Extension here is assisted by hamstring part of the adductor magnus and to some extent by the adductor brevis.
The joint at the distal end of the femur and proximal end of the tibia where the patella overlaps is called the knee joint. It is a hinge joint that allows for flexion and extension of the leg.

The rectus femoris becomes active in a leg extension because one of the actions of the rectus femoris is hip extension, as well as knee extension. The rectus femoris crosses both the hip and knee on the anterior side of the body. When the leg is extended it is one of the primary movers, whether it be straight leg extension, in which case it is the rectus femoris, illium and psoas muscles. In knee extension the rectus femoris works in conjunction with the other 3 quadriceps. However, in the case of a seated leg extension the rectus femois is less active, due to it already being shortened for the hip extension.
The weight increments available on the leg extension machine typically range from 5 to 20 pounds.
The leg extension exercise primarily targets the quadriceps muscle group in the front of the thigh.
