Most of the time, skeletal muscles are involved in voluntary muscle movement. When you lift an object, it is voluntary. Involuntary means you do not control the movement. The beating of your heart and movement of your digestive tract are both examples of in voluntary muscle action.

Direction: Some of the action like moving our limbs , fingers, moving...
The muscles which perform voluntary action are skeletal muscles.
Skeletal muscles, also known as striated muscles, are responsible for the voluntary movements of the body. They are attached to the bones of the skeleton and are under conscious control. These muscles are responsible for actions such as walking, running, lifting objects, and moving our limbs, fingers, and neck.
Explanation:
1. Skeletal Muscles:
Skeletal muscles are attached to the bones of the skeleton through tendons and are responsible for the movements of the body. They are called skeletal muscles because they are generally connected to the skeleton, and their contractions cause movement of the bones. These muscles are under voluntary control, which means we can consciously control their movements. For example, when we decide to walk or lift an object, our brain sends signals to the skeletal muscles involved, and they contract and relax to perform the desired action.
2. Smooth Muscles:
Smooth muscles, also known as involuntary muscles, are found in the walls of organs and blood vessels. Unlike skeletal muscles, smooth muscles are not under conscious control and are responsible for involuntary actions such as digestion, blood circulation, and contraction of the uterus during childbirth. Therefore, smooth muscles do not perform voluntary actions.
3. Cardiac Muscles:
Cardiac muscles are found in the walls of the heart and are responsible for its contractions. Unlike skeletal muscles, cardiac muscles are also involuntary and not under conscious control. The contractions of the heart are regulated by the cardiac conduction system, which coordinates the rhythm and strength of the heartbeat. Therefore, cardiac muscles do not perform voluntary actions.
Conclusion:
In conclusion, the muscles that perform voluntary actions are skeletal muscles. These muscles are under conscious control and enable us to move our limbs, fingers, and other body parts at will. On the other hand, actions such as blinking of eyes and contraction and relaxation of the heart are involuntary and controlled by other types of muscles (smooth muscles and cardiac muscles).
