Lateral Sacs - enlarged regions of the sarcoplasmic reticulum that come into close contact with the transverse tubules.
Background image of page 4
Foot Proteins - proteins that span the gap between the lateral sacs and the transverse tubules and mediate a change in permeability to Ca ++ by the lateral sacs. Also known as ryanodine receptors because they are locked open by the plant chemical ryanodine.

Dihydropyridine Receptor - receptor proteins in the transverse tubule membrane that come into contact with the foot proteins. They are voltage dependent and gate the change in permeability of the foot proteins to Ca ++ .
