|
Junctional sarcolemma reticulum |
Ryanodine receptors, Ca channels, phase 3 L type Ca channel dihydropyridine Ca influx stimulated Ca release → contractile proteins & contractions |
|
|
Longitudinal SR |
Ca uptake into SR, via SERCA, Sarcoplasmic Endoplasmic Reticulum Ca ATPase, ATP dependent Ca pump → myofibrillar relaxation |
|
|
beta stimulation & relaxation |
Activate kinase → phosphorylate & deactivate Phospholamban →disinhibit SERCA →Ca uptake & myofibrillar relaxation |
