voluntary, a typical person can move it at will.
The upper arm is under voluntary control. This means that you can consciously move and control your upper arm muscles when you want to, such as when you reach for something or lift an object.
Two kinds of body movement are voluntary and involuntary. Voluntary movements are consciously controlled, such as raising an arm to wave. Involuntary movements occur without conscious control, like the beating of the heart.
Skeletal muscles are mainly voluntary. Because you can consciously moveyour arm, legs, head, speak, etc.. But they can also be involuntary examples is muscle spasms, reflexes, shivering.
The skeletal muscle is voluntary. Voluntary muscles are the muscles that you have the ability to control. This includes moving your arm, chewing, or moving your legs. Involuntary muscles are muscles you have no control over. A good example of that would be smooth muscles that help with digestion.
It is voluntary because your voluntary muscells in the arm are preforming this action.
It means that you naturally move your arm with out thinking that your going to move it. There are two types of muscles; voluntary muscles and involuntary muscles. Voluntary muscles are muscles that you think about to move sometimes and involuntary muscles are muscles that you don't think about moving. An example of an involuntary muscle would be your heart and an example of a voluntary muscle would be your arm even though you don't really have to think about it when you move it.
An example of using voluntary muscles is when you lift your arm. You have decided to do this action.
Involuntary muscles act on their own, like the heart muscles. Voluntary muscles you control, like the arm muscles.
Involuntary muscles are not under you conscious control they are responsible for essential activities such as breathing and digesting food. Voluntary muscles are under your conscious control smiling, turning a page in a book are controlled by voluntary muscles.
It is involuntary because you cannot control it; meaning that you cannot volunteer it to move like moving your arm. Please give me a trust point, thanks.
It depends. But, the triceps are 2/3 of your upper arm.
When it does something that you didn't even want it to. Every action will generally have to go through your brain, and if you didn't send a request to lift your arm up and it does it anyway, that is involuntary.
