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.
The purpose of transposition is due to balance the capacitance of the line so that electro-statically induced voltages balances out in the transposed lines. Under balanced condition the conductors magnetic field linking an telephone line is shifted by 120o out of phase.s the power lines are transposed, over the length of one complete transposition cycle (three different positions of the power conductor) of power line, the net voltage induced in the telephone line is zero.
