The joint action in leg extensions is knee extension, where the angle between the thigh and lower leg decreases. The main muscles involved in this action are the quadriceps, specifically the vastus medialis, vastus lateralis, vastus intermedius, and rectus femoris. The movement primarily occurs at the knee joint.
No, the rotator cuff is a group of muscles and tendons that support and stabilize the shoulder joint, not the elbow joint. The flexibility at the elbow joint is mainly due to the action of different muscles like the biceps and triceps.
The joint in the leg that is equivalent in the shoulder is the Ankle
The joint between the leg and the hip is the hip joint, which is a ball-and-socket joint. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation of the leg. The hip joint is supported by a network of muscles, ligaments, and tendons that help stabilize the joint during movement.
knee
The knee joint is located in the leg at the knee. It is a type of hinge joint.
Leg extensions typically use a third-class lever system, where the effort is applied between the fulcrum (knee joint) and the resistance (weights being lifted). The quadriceps muscles contract to extend the knee joint against the resistance, providing the force needed for the movement.
Some examples of single joint exercises for targeting specific muscle groups include bicep curls for the biceps, tricep extensions for the triceps, leg extensions for the quadriceps, and calf raises for the calf muscles.

No, you should not straighten your leg after a knee subluxation as this action could further hurt your knee joint.
Mammals have a joint in the middle of the leg that is called a knee. In humans this joint allows the leg to bend backwards.
I do believe the joint in the middle of your leg is your knee.

There are three joints in the human leg: the hip joint, the knee joint, and the ankle joint.

If your referring to the knee joint it is the tibiofemoral joint.
