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.
Each electrical signal normally begins in a group of cells called the sinus node or sinoatrial (SA) node. As a signal spreads from the top of the heart to the bottom, it coordinates the timing of heart cell activity. First, the heart's two upper chambers, the atria (AY-tree-uh), contract. This contraction pumps blood into the heart's two lower chambers, the ventricles (VEN-trih-kuls). The ventricles then contract and pump blood to the rest of the body. The combined contraction of the atria and ventricles is a heartbeat.
