Those muscles are called voluntary muscles because you choose to move them, but not all of the muscles in your body work that way. The muscles of your heart, organs and other internal structures are involuntary muscles because they are hard at work regardless of what you are doing; they ...
The muscles of the vertebrates can be classified into three major types: (1)skeletal muscle, (2)smooth muscle, and (3) cardiac muscle. The skeletal muscle is the muscle attached to theskeletonand is responsible for the voluntary movement of theskeletal system. The smooth muscle is the type ...
Cardiac muscle is unique because it is striated, like skeletal muscle, yet involuntary, like smooth muscle. Skeletal muscle controls the body's movement and is generally under conscious, or voluntary, control. The internal organs, on the other hand, with the exception of the heart, are made ...
or layers in tubular systems, such as arteries and veins (see Blood Vessels), the gastrointestinal and respiratory tracts, and thegenitourinary tracts. The activities of the smooth muscles are not under conscious control; rather they are coordinated by the autonomic (involuntary) nervous system. ...
Features of cardiac muscles Cardiac muscles are involuntary muscles. They are involved in continuous rhythmic contraction and relaxation. Cardiomyocytes or the cardiac cells are uninucleate, cylindrical, and elongated. Cardiac muscles display faint cross-striations which do not get fatigued under normal ci...
These stripes are called striations. Skeletal muscles usually move because the brain has sent a conscious message to them telling them what to do. This is called voluntary movement. Another type of muscle is smooth muscle. Unlike skeletal muscle, smooth muscle does not have str...
What is the difference between voluntary and involuntary muscles? Voluntary muscles are those whosemovement can be controlled at will or conscious control, while involuntary muscles are those whose movement can not be controlled at will or without conscious control or that work involuntarily, i.e.,...
This is why doctors always insist that people with high blood pressure find a way to lower it. They either recommend losing weight, getting out of a stressful situation, or taking blood pressure medication. I have high blood pressure, but since mine is caused by a kidney disease that restric...
Such muscles are called voluntary muscles, and as explained above, they move on command. Some other muscles help you eat and digest food. Some other muscles, like your heart, pump blood throughout the day; but do these muscles work on our command? These muscles are called involuntary ...
Cardiac muscles are (a) Striated, voluntary with syncytial condition (b) Unstriated, involuntary, uninucleated (c) Striated, involuntary with intercalated disc (d) Involuntary and unstriated View Solution Assertion: Cardiac muscles have striations and fiber is nucleated and involuntary. Reason: Inter...
