does skeletal muscle have calcium induced calcium release?

You mean ryanidine receptors? I think those are consistent across all muscles, right? That is, after all, the system of calcium release from sarcoplasmic reticulum.

hmmm i mean is it due to calcium release?

Calcium-induced calcium release (CICR) describes a biological process whereby calcium is able to activate calcium release from intracellular Ca2+ stores (e.g., endoplasmic reticulum or sarcoplasmic reticulum). Although CICR was first proposed for skeletal muscle in the 1970s,[1] it is now known that CICR is unlikely to be its primary mechanism for activating SR calcium release. Instead, CICR is thought to be crucial for excitation-contraction coupling in cardiac muscle[2] and it is now obvious that CICR is a widely occurring cellular signaling process present even in many non-muscle cells, e.g. in the insulin-secreting pancreatic beta cells[3] and many other cells. Since CICR is a positive-feedback system, it has been of great interest to elucidate the mechanism(s) responsible for its termination.

We don't relaly know anything for sure lol, thanks
