(SER) surrounding each myofibril. Historically, this SER was calledsarcoplasmic reticulum.Terminal cisternae of SER are closely associated with T tubules at foot processes that can be visualized by electron microscopy. Together, T tubules and SER constitute a signal-transducing apparatus that converts...
but had no effect on the expression of other Ca2+handling proteins localized to the SR or t-tubules (Fig.1dand Fig.S1). Since Mg29 has been described as both a t-tubule and SR-resident protein in skeletal muscle11, and it was previously identified as a potential regulator ...

In basal muscle, Glut4 was highly enriched in membranes of the transverse tubules and the terminal cisternae of the triadic junctions. Less than 10% of total muscle Glut4 was present in the vicinity of the sarcolemmal membrane. Insulin treatment increased the number of gold particles associated ...
The connexion between these tubules and the terminal cisternae (triads) of the sarcoplasmic reticulum, suggest that this phenomenon seems to be a proliferation of the transversal-tubular system due to the partial denervation. Only a mechanical displacement of the T-tubules as a result of the ...

Intermyofibrillar SR contained three regions: 1) fenestrated collars overlying the M-band region, 2) terminal cisternae overlying the A-I region, and 3) a three-dimensional anastomosed tubular network overlying the Z-band region. Longitudinal and/or transverse SR tubules connected these regions. ...
: proliferated terminal cisternae; tubular aggregates (presumably proliferated longitudinal components of the s.r.) with (Ib), or without internal tubules (Ic). Also, there wre two types of tubules of much larger diameter surrounded by 100 filaments (IIa and IIb), and closely packed cisternae ...
