smooth muscle
The muscle that is responsible for most of a movement is called a prime mover. It may also be called an agonist.
Muscle cells are formed in such a way that they contract and shorten. By doing this they produce a movement of one type or another. Skeletal muscle cells (called fibers) pull one bone towards another bone, smooth muscles fibers shorten as well but they don't act on bones. They produce waves of movement.

The muscle action you are referring to is called adduction. This movement brings the thumb towards the palm of the hand. Adduction is an important function that allows for gripping and grasping objects with the hand.
Muscle tissue
origin
The tension of muscle fibers is called muscle tension. It refers to the force generated by a muscle when it contracts. Muscle tension is necessary for movement, posture, and stabilization of the body.
the prime mover is the muscle responsible for most of the movement in a group of muscles; called the chief muscle.
A muscle that acts as a helper to accomplish a particular movement is called a synergist. Synergists assist the primary muscle, known as the agonist, by stabilizing joints and facilitating smooth movement during actions. They play a crucial role in ensuring coordinated muscle function and can also help to fine-tune the movement.
synergist
The muscle that is primarily responsible for bringing about a particular movement is called the prime mover or agonist muscle. It is the main muscle that contracts to create the desired movement at a joint. Antagonist muscles work in opposition to the prime mover to control the movement and prevent injury.
