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.
of His, which conducts the signal through the interventricular septum towards the apex of the heart. Soon after entering the interventricular septum the AV bundle bifurcates into two separate branches. The conduction of the electrical signal through the interventricular septum, coupled with the slow conduction velocity of the AV node, causes a delay from when action potentials form in atrial myocardium and when they form in the ventricular myocardium (and subsequently in when the two sets of chambers contract) called the atrioventricular delay. This delay ensures that atrial systole is complete at the onset of ventricular systole. Once the signal reaches the apex of the heart it is conducted up the lateral walls of the ventricle through branched tracts of pacemaker cells called Purkinje fibers, which distribute the electrical signal to the ventricular myocardium. Electrical changes occurring during the cardiac cycle can be monitored from the surface of the body in a recording called an electrocardiogram (ECG, or EKG). A normal
