Smooth muscles are found in blood vessels and in organs (ie the bladder), and is stimulated by the autonomic nervous system, the control system for involuntary reactions. Smooth muscles can also be controlled by hormones, neurotransmitters and other chemicals such as calcium and potassium. Depending on what chemical binds to the muscles receptor sites will change what type of reaction occurs within the muscle itself. For example if you were frightened, your heart would beat faster, you would breathe deeper -- and not because you wanted to do it, but because your body automatically reacted to the stimulus. That is what the autonomic nervous system relies on -- automatic responses.
No, not usually. Smooth muscles are mostly involuntary and cardiac work without conscious control. You can contract and relax skeletal muscles.
Smooth: located in hollow internal structures like blood vessels, stomach, intestines, and urinary bladder-usually can't control
Cardiac: forms the bulk of the wall in the heart-can't control
Skeletal: found attached to the bones-can control them.
No. Only skeletal muscle is under voluntary control. Cardiac muscle, although striated like skeletal muscle, is also not voluntary.
NO you cannot consciously control smooth muscle. It is an involuntary muscle.
extra info: you can control the skeletal muscle but you cannot control cardio and smooth muscles :)
yes. Smooth muscles are another name for involuntary muscles.
yes
Voluntary muscles are skeletal muscles (under somatic control) and involuntary muscles involve the heart, smooth muscles and anything under autonomic control.
No.
yes it is.....
Skeletal muscles that move our bones are under voluntary control. They have a microscopic appearance with striations so they are called striated muscle. Some striated muscles such as muscles of the eyelids (the obicularis muscle of the eye lid) are under both voluntary and involuntary control... you can be blinking by thinking or blink without thinking. This is partly because the obicularis has some specialize "smooth" involuntary muscle fibers mixed in. There are many muscles called smooth muscles that are part of organs such as the stomach and intestine that are not under voluntary control. This muscle has no microscopic striations and is called smooth. The last main type is cardiac that is somewhat like striated but is typically not under voluntary control.
voluntary muscles....mostly skeletal mauscles
Skeletal muscles are under voluntary control; smooth muscles and cardiac muscles aren't.
Skeletal or voluntary muscles attach to the skeleton and allow movement. In contrast, smooth muscles are not under voluntary control.
Most muscles are under voluntary control, save for reflexive responses. However, the muscles that operate the heart and lungs, for example, are autonomic or under non-voluntary control.
Skeletal muscles, like biceps, are under voluntary control. Smooth muscle, like the diaphragm, and cardiac muscle are involuntary. Thanks for using Answers.com!
Voluntary muscles help you to perform voluntary movements.
Muscles that are under your conscious control are voluntary, such as flexing your elbow. The ones under unconscious control are either reflexive or involuntary, such as the muscles that move your food through your digestive system, or make your heart beat.
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! :]
