why do you regard as the details of skeletal muscle and cardiac muscle contraction.?

why do you think the details of skeletal muscle and cardiac muscle contraction are justly well embedded, but knowledge of contaction of smooth muscle is more constrained?why do you regard as the details of skeletal muscle and cardiac muscle contraction.?
All of the above are well couched, it's just that skeletal and cardiac mucsle are more complicated, so there is more information on them. Smooth muscle contraction can function solely on its intrinsic plexus, its built-in on edge system that only receive fine tuning from the para and sympathetic nervous systems. It even have its own immune system, Peyer's Patches for example.
