Answer:
True
Explanation:
The compound schedule takes two or more basic schedules that occur on reverse, usually at random level, a discriminating stimulus is correlated with the presence and absence of the element of the schedule and given the reinforcement for getting the response . In mixed schedule reinforcement consists two or more schedules that occur in alternating usually random sequence level. No discriminating stimulus is correlated with the presence or absence of each element of the schedule. Reinforcement is given to the response requirement of the elements in the effects at any time that is given by the subject.
During closed kinematic chain for knee flexion, the femoral condyles roll <u>posteriorly </u>and glide <u>anteriorly</u>.
The patella shifts from the superior (shallower) to the inferior (deeper) section of the trochlear groove during knee flexion. As a result, across the range of knee motion, the patella's articulating surface on the femur changes.
The translation of the femoral condyle during knee flexion is smaller at the medial compartment than at the lateral side of the knee, according to many early investigations. 4, 6, 28 The medial-pivoting rotation of the knee during flexion is the term used in literature to describe this kind of knee movement.
The femur will roll anteriorly and glide posteriorly on the stable tibial base in a closed kinetic chain, controlling the movement of the tibia.
