Why can smooth muscle contract over a wider range of resting lengths than skeletal muscle?
A)smooth muscle has tight junctions to keep the fibers anchored
B)in smooth muscle the actin and myosin are more loosely organized
C)in smooth muscle intercalated discs are found between the fibers
D)in smooth muscle the T tubules allow efficient transmission of the action potential
E)smooth muscle has fewer layers than skeletal muscle
