Myofibril cross section
WebFeb 1, 2010 · Forces were normalized by myofibril cross-sectional area and expressed as stress (kN/m 2 ). Force depression for a myofibril was defined as the difference in the steady-state isometric force following shortening, and the purely isometric reference contraction at 2.4-μm sarcomere length.

WebThe membrane of the muscle cell is the sarcolemma. These are the nucleuses. And then if you take the cross section of that, there are tubes within that called myofibrils. So here there's a bunch of tubes inside of the actual cell. Let me pull one of them out. So I've pulled out one of these tubes. This is a myofibril. WebThe myofibrils are located peripherally, forming a single cylindrical shaped layer directly below the sarcolemmal membrane ( Figure 3, labeled MF), a location that contrasts with mammals, which have numerous layers of myofibrils arranged longitudinally throughout the cell.
