Involuntary muscles are found in the smooth and cardiac muscles; they work with the nervous system and moving this with out actually knowledge of it happening. Such as our heart we can not control when it pumps or when it takes in blood and empties blood it just happens automatically. Its just the way God made us isn't it amazing how well designed we are. So why don't people believe in a God and don't believe in him and trust him. Can you not see the world around you all the creation and everything if there is no God how can there be such a beautiful and creative world as this. If your argument is "all the wrong and evil there is How can there be a God?" this is easily answered by the bible that sin by man came into the world and you if you don't believe in God are helping Satan and all this sin so if this has not answered question then read the bible and discover the truth for yourself and if you believe another religion take a look for yourself and see if your religion makes sense or if you just believe it because you are told it. Think is there a God?
This question relates to the topic of biology of muscles. The body parts are moved by muscular contraction. Two types of muscles are found in the mammalian body; voluntary and involuntary muscles. Involuntary muscles are those muscles which are not under the control of the will. They are found in the alls of the alimentary canal, arteries and veins. Like the skeletal muscle, an involuntary muscle consists of numerous muscle fibers. Each muscle fiber is spindle shaped, thick in the middle and tapering gradually towards the ends. It has only a single nucleus in the cytoplasm. Cross striations are absent in these muscle fibres, hence they are called unstraited or smooth muscles. Unstraited muscles are capable of slow and sustained contractions.
Cardiac muscle is a special form of involuntary muscle. It occurs only in the walls of the heart. Cardiac muscle fibres are fairly short and have very faint cross striations. The fibers do not occur separately, but they branch and unite to form a branching network. Heart muscle can contract rhythmically without nervous stimulation. This can be noticed, when an animal or a man dies, even though this brain and nervous system has stopped working, the heart still beats rhythmically.
The heart is a cardiac muscle and an involuntary muscle. Involuntary muscles are muscles that work without the help of the human e.g. Arms, legs, fingers and toes The heart doesn't need help to work, like a voluntary muscle, therefore it is an INvoluntary muscle. It is also a cardiac muscle. During cardiac arrest a victim loses consciousness, stops normal breathing and loses pulse and blood pressure.
Involuntary muscles are not attached to bones usually your not aware that these muscles are working for example your involuntary muscles in your stomach contract and relax to mash and squeeze the food you eat
