Those are not under our control
If such things were voluntary we would not exist.
we canot control that muscles
It is most definitely involuntary. You do not have to make your stomach contract every time you eat something.
Smooth muscles produce a slow movement of the stomach mixing the contents. This muscle is not voluntary as you do not have to think about it as you do with your legs and arm muscles.
The muscles used for speech, chewing and swallowing are in a sense both voluntary and involuntary muscles for we use them both consciously and reflexly. However, the term voluntary muscle usually refers to the striated skeletal muscles as opposed to the smooth muscles of the interior organs (like the stomach or intestines).
Voluntary
Skeletal muscles are voluntary muscles.
you have 2 different types of muscle... voluntary and involuntary. Voluntary muscles like you biceps, triceps, quads etc. move when you want them to and involuntary muscle like you stomach and you lungs move by themselves and you have no control
Your involuntary muscles are muscles like your smooth muscle (stomach) and your cardiac muscle (heart), which are under autonomic control. Your skeletal muscles are the muscles which are voluntary since you have complete control over them! :]
yes
Skeletal muscles are the only voluntary muscles
voluntary, you control what it does.
