In: Tissue and Cell, 2004, vol. 36, no. 4, p. 249-252

In the present investigation the sole plate area of motor end plates of the frog is ultrastructurally examined with different postfixation methods. We concentrated in this case on the proof of the smooth and rough sarcoplasmic reticulum of the sole plate. The relations of the smooth and rough sarcoplasmic reticulum to subsynaptic folds and the local T-system and its connections to diads and...

About the T-system in the myofibril-free sarcoplasm of the frog muscle fibre

Voigt, Tilman ; Dauber, Wolfgang

In: Tissue and Cell, 2004, vol. 36 (4), p. 245-248

Previous investigations of the T-system in skeletal muscle fibres described the inter-myofibrillar relationships between T-tubules and the sarcoplasmic reticulum. They disregarded the arrangement of the T-system in the myofibril-free sarcoplasm in the area of muscle fibre nuclei. In the present investigation, the T-system was filled by means of lanthanum incubation and the myofibril-free...
