Cell membrane of the muscle fiber
WebFeb 26, 2024 · The cell membrane of a muscle cell is called the sarcolemma, which surrounds the sarcoplasm or cytoplasm of the muscle fiber. Because the whole muscle fiber must contract at the same time, the signal (action potential) is conducted through the cell by transverse tubules (T tubules) which have the same properties as the sarcolemma. WebThe postsynaptic muscular membrane (sarcolemma) is covered, on the extracellular surface, with a layer of electron-dense material, the basal lamina (Figure 6.12a,c). This …
