Students have asked these similar questions

Striations are found in the cytoplasm of which type(s) of muscle tissue? Select all that apply. A. Skeletal muscle B. Cardiac muscle C. Smooth muscle

Skeletal, smooth, and cardiac muscle are similar in that they all _____. A are divided into motor units B require calcium in order to contract C undergo mitosis frequently to replace dead or damaged cells D have small round cells connected by gap junctions

In muscle cells, magnesium ions compete with calcium ions for binding sites on troponin molecules. If a person has too high a concentration of magnesium ions in the blood, magnesium ions can prevent calcium ions from binding troponin. A) What effect would this have on muscle contraction (strengthen, weaken, or no effect)? B) Use your knowledge of how muscle fibers contract to explain your answer in part A.
