The functions of a fixator muscle is the stabalizing of the orgin of the prime mover so that the prime mover can act more efficiently. Fixators steady the proximal end of a limb while movements occurs at the distal end.
EX: The scapula is a freely movable bone that serves as the orgin for several muscles that move the arm. When the arm contracts the scapula must be held steady.

The fixator of a muscle stabilizes the muscle at the point of origin.

The fixator is one of many muscles used during situps. The fixator muscle stabilizes one part of your body when you move another part.
i think is the deltoid muscle but I'm not sure tbh
The fixator muscle for back extension is primarily the transversus abdominis. This muscle stabilizes the pelvis and lumbar spine during movements, allowing the extensor muscles of the back, such as the erector spinae, to effectively extend the vertebral column. Additionally, the multifidus also plays a role in stabilizing the spine during back extension.
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.
The trapezius muscle can function as both a fixator and a synergist, depending on the movement being performed. As a fixator, it stabilizes the scapula during arm movements, allowing other muscles to work efficiently. As a synergist, it assists in shoulder elevation and retraction, working alongside other muscles like the deltoids and rhomboids. Its versatile role makes it essential for various upper body movements.
Antagonist: Controls movement, opposite of prime mover Prime Mover: Main muscle that is directly responsible for movement Synergist: Aids in movement of muscle
When the triceps muscle contracts, the fixator is typically the muscles that stabilize the shoulder joint, such as the rotator cuff muscles. These muscles help maintain the position of the shoulder while the triceps extend the elbow. This stabilization allows for efficient movement and prevents unwanted motion during the contraction of the triceps.
Some examples are smooth muscle and cardiac muscle.
