One obvious similarity is that they are all muscles. This means that they all have actin and myosin which works together to contract a muscle. All types of muscles use this method to make something move.
In skeletal muscle, the contraction allows the bone to move, thereby allowing your body to move. In the heart, the cardiac muscle pumps the blood into the arteries. The smooth muscles in blood vessels are used to pump blood in one direction (in veins, which is in low pressure, there are valves which prevents backflow). The smooth muscles in digestive organs use the muscle to move the food through the digestive track, or the alimentary canal.
Both skeletal and smooth muscle contain actin and myosin filaments, which form cross-bridges in order for the muscle to contract. Both also contain a sarcoplasmic reticulum - which stores calcium. In both muscle types, this calcium allows for cross-bridge formation between the actin and myosin filaments when it is released (it acts directly on myosin in smooth muscle and acts indirectly in skeletal muscle).
Smooth muscles are usually less metabolically active and so not as dark/red as skeletal muscles. They also aren't as striped at the microscopic level.
they are MUSCLES lol
Smooth muscle shortens and stretches to a greater extent than does striated muscle.
There is none. The only type of non-striated muscle is smooth muscle and smooth muscle is involuntary muscle.
Here we are talking about the surface of the muscles..... Smooth muscles have smooth surface while striated muscles have rough surface.....
Smooth muscle is the muscle inside of the digestive system so it has to be involuntary.
smooth muscle. stomach
no, it is branching and striated.
no..only skelet muscle.....
Skeletal muscle is striated and voluntrary. Smooth muscle, as is found around the blood vessels and in many organs, is not striated and involuntary. The heart (cardiac muscle) is the only place you have striated involuntary muscle.
There is nothing really called 'cardiac smooth muscle'. Cardiac muscle is striated like skeletal muscle but it is not under your control like skeletal muscle is. It acts more like smooth muscle because of this reason. But we only use the terms smooth muscle, striated (skeletal) muscle or cardiac muscle.
Muscle.
Smooth muscle is not striated.
