This is an issue that deserves attention, as research examining iron levels in Americans shows that more people have iron levels that are considered too high, than levels that are deficient.

The skeletal muscle has a common contraction called a synctium (and no gap junctions).owever, their major difference is that the skeletal muscle is controlled by the somatic nervous system, and the cardiac muscles are, by nature, involuntarily controlled. Besides their overall different locations within the body, these two muscles also have many differences in their cellular structures.
