All muscle cells contain striations..

All types of striated muscle contain a branched network of membrane invaginations called T-tubules that enable synchronous calcium release throughout the entire cell volume. The T-tubules contact the sarcoplasmic reticulum (SR) between the A and I bands in skeletal muscle and at the Z-disc in cardiac muscle. ...
