WebTwo simple conclusions follow: 1) reflexes should not be measured at rest, if the goal is to understand their role in behavior because the results may be very different at rest during the movements of interest and 2) although postactivation depression can be demonstrated in both animal and human experiments, attributing functional significance to … WebA stretch reflex is a type of muscle reflex, which protects muscle against increases in length that can tear and damage muscle fibers. The primary purpose of the patellar reflex – the stretch reflex of the quadriceps femoris muscle – is to prevent excessive stretching of the quadriceps. The patellar reflex is illustrated in Figure 1.
