Do Smooth Muscle Cells Have Sarcoplasmic Reticulum? Vascular smooth muscle cells do not contain the complex t-tubule/sarcoplasmic reticulum system common to striated muscles, but rather they contain a significant number of invaginations along the plasma membrane called caveolae, which serve a similar, albeit less developed role to increase the cellular surface: volume … Do all

Do Myofibrils Have Sarcolemma? Do Myofibrils have Sarcolemma? Within the sarcoplasm of each individual muscle fibre are approximately 1,000 to 2,000 myofibrils. Composed of the contractile proteins actin and myosin, the myofibrils represent the smallest units of contraction in living muscle. … complex multilayered structure called the sarcolemma. Where can sarcolemma be found? The sarcolemma
