Dyadic junction
WebDyadic junction which consisted of a single T-tubule paired with a terminal cisterna of the sarcoplasmic reticulum is found mainly at the A-I level of sarcomere. Each cell is arranged to form multiple connections with neighboring cells through the intercalated discs. These specialized junctions Webreleased by 106 ryanodine receptors clustered in 104 dyadic junctions near the sarcomeric Z lines (1, 2). In each dyadic junction, the ryanodine receptors ("100) are located in the junctional membrane of the sarcoplasmic reticulum (SR) in close apposition to "20 L-type Ca2+ channels (DHP recep-tors) located in the transverse tubular membrane (2 ...
