The primary muscle responsible for finger flexion is the flexor digitorum profundus, which flexes the distal joints of the fingers. Additionally, the flexor digitorum superficialis assists in flexing the proximal joints. These muscles work together to allow for the bending of the fingers, enabling grasping and gripping actions.

Elbow flexion, shoulder flexion and supination of the forearm.
Trunk flexion & unilateral trunk flexion.
Flexion and extension.
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.
Muscle extension is when a muscle lengthens, while flexion is when a muscle shortens. Extension helps with stretching and increasing flexibility, while flexion helps with bending and contracting. Both movements are important for maintaining range of motion and strength in the body.

The antagonist is your mom
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.
