I know skeletal muscle has SR, but does cardiac muscle and smooth muscle also have SR??

cardiac muscle does have SR, but it isn't sufficient to supply the msucel with all of its calcium. thats why the heart needs extracellular Ca+ in order to contract.

smooth muscle does have an SR but it is way under develoepd in comparison to cardiac and skeletal muscle.
