The muscle tissue that is striated is (a) skeletal muscle, (b) cardiac muscle, (c) smooth muscle, (d) cardiac and skeletal muscle, (e) all three types of muscle tissue.
Large muscle fibers that are multinucleated, striated, and voluntary are found in (a) cardiac muscle tissue. (b) skeletal muscle tissue. (c) smooth muscle tissue. (d) a, b, and c are correct.
As blood vessels increase in diameter, the amount of smooth muscle decreases and the amount of connective tissue increases. Explain why. (Hint: Remember Laplace's law)
