The muscles that mainly pull arms backward are the triceps. These are muscles that are found on the back of the upper arm.
When she pulls her arms in, her rotational kinetic energy increases because her moment of inertia decreases, causing her to spin faster.
Yes, angular momentum is conserved when a spinning ice skater pulls in their arms. This is because the skater's rotational speed increases as they bring their arms closer to their body, balancing out the decrease in their moment of inertia.
When a spinning skater pulls in her arms to turn faster, her angular momentum is conserved. Angular momentum is the product of an object's moment of inertia and its angular velocity. By pulling her arms in, the skater decreases her moment of inertia, causing her angular velocity to increase in order to maintain a constant angular momentum. This is similar to the principle of conservation of angular momentum seen in other rotating systems.
The myosin myofilament pulls on the actin myofilament during muscle contraction. This interaction, known as the sliding filament theory, results in the shortening of the sarcomere and muscle contraction.
When a horse pulls a cart, the action is on the horse. The horse exerts force on the cart through its harness, which causes the cart to move. This action is a result of the horse's muscle power and body strength.
trapezius
Pectoralis Major
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.

The muscle responds and pulls on a bone by way of a tendon. It can not react until the nerve tells it to.
Diaphram

you have then stretched your tendon / muscle beyond the normal range .
When one muscle pulls, the other muscle relaxes.
