This allows the load cell to be hidden in the base of the pedals, where it is bolted to another piece of timber glued across the base. The clutch has a regressive action, with a linkage that pivots upwards on a couple of sealed bearings. The load cell is anchored at the top rear of the base. As the pedal moves into itâs travel, the stiffness decreases and the spring rotates upwards on a pair of bearings (hidden behind the bolts which are covering the spring in the pic below). You can see the 608-2RS bearings in the spring backplate, epoxied in place.
Intercalated discs Histology/Morphology. The cardiac muscle is normally found only in the heart. Here, the myocardial cells usually appear short, branched, and closely interconnected to form a continuous fabric. The cross-bands, however, get heavily stained between the adjacent cells during histological examination of the cardiac tissue.
How does excitation-contraction coupling in a cardiac muscle cell differ from that in a skeletal and smooth muscle fiber. Cardiac--depolarization due to influx of calcium ions through voltage gated channels (L type calcium channels which are modified versions of the DHP receptors in skeletal muscle). Cardiac--instead of being open directly by voltage as in skeletal muscle, cardiac are opened by binding of trigger calcium in cytosol.
