The antagonists would be those muscles that cause knee flexion. Hamstrings (biceps femoris, semimembranosus, semitendonosis) are the primary knee flexors, and would thus be antagonists to knee extension.
The primary muscles involved in hip extension are the gluteus maximus and the hamstrings. The primary muscles involved in knee flexion are the hamstrings and the gastrocnemius.
Flexion and extension are movements that occur at joints in the body. Flexion decreases the angle between two body parts, while extension increases the angle. Flexion typically decreases the range of motion, while extension increases it. In terms of muscle activation, flexion usually activates muscles on the front side of the body, while extension activates muscles on the back side.
The supinator muscle is a muscle in the forearm that is not directly responsible for flexion or extension of the arm. Its primary function is to rotate the forearm in a movement called supination, where the palm faces up.

When a muscle contracts it causes flexion and when muscles relax they cause extension
Shoulder extension involves moving the arm backward, increasing the angle between the arm and the body, while shoulder flexion involves moving the arm forward, decreasing the angle. Shoulder extension typically has a greater range of motion compared to flexion. Different muscles are activated during each movement: shoulder extension primarily activates the latissimus dorsi and teres major muscles, while shoulder flexion primarily activates the anterior deltoid and pectoralis major muscles.
Shoulder flexion involves raising the arm forward and upward, while shoulder extension involves moving the arm backward and downward. Shoulder flexion typically has a greater range of motion compared to extension. Different muscles are activated during each movement, with shoulder flexion primarily involving the anterior deltoid and shoulder extension primarily involving the latissimus dorsi and teres major muscles.
Flexion movements of the back involve bending forward, while extension movements involve arching backward. Flexion can help stretch the back muscles and improve flexibility, but excessive flexion can strain the spine. Extension movements help strengthen the back muscles and improve posture, but too much extension can also lead to strain. Balancing both movements is important for overall spinal health and function.
Neck flexion is the movement of bringing the chin towards the chest, while neck extension is the movement of tilting the head back. Flexion can help strengthen the front neck muscles and improve posture, but excessive flexion can strain the neck. Extension can strengthen the back neck muscles and improve range of motion, but too much extension can also lead to strain. Balancing both movements through proper exercise and posture can help maintain the overall health and function of the neck.
Extension and flexion are movements that occur at joints in the human body. Extension involves straightening a joint, increasing the angle between two body parts. Flexion, on the other hand, involves bending a joint, decreasing the angle between two body parts. The range of motion in extension is typically greater than in flexion due to the anatomical structure of the joints and surrounding muscles.
The antagonist muscle in the flexion of the knee is the quadriceps muscle group. When the knee is being flexed, the quadriceps relax to allow the hamstrings to contract and bring about the flexion movement.
