The knee joint functions as a stabilizer for the lower extremity during weight bearing and allows large range of motion for various functional activities. The two primary articulations of the knee joint are the tibiofemoral joint and the patellofemoral joint.
1. electrocardiogram recorded between one limb and two other limbs. The augmented leads are designated aVF, aVL, and aVR for recordings made between the foot (left), left arm, and right arm, respectively, and the other two limbs. The definition information for augmented lead is provided by Stedman's.
In the NPN transistor in what is called active mode, the baseâemitter voltage and collectorâbase voltage are positive, forward biasing the emitterâbase junction and reverse-biasing the collectorâbase junction.he remainder of the holes recombine with electrons, the majority carriers in the base, making a current through the base connection to form the base current, . As shown in the diagram, the emitter current, , is the total transistor current, which is the sum of the other terminal currents (i.e., I E = I B + I C).
