Based on the Neurophysiological Properties of the Contractile Components of Muscle

Multiple Choice

Based on the neurophysiological properties of the contractile components of muscle, a high-intensity, quick stretch of a muscle-tendon unit is believed to create phasic elevation of tension in the stretched muscle by:

A) Facilitating the muscle spindle via the Ib fibers.
B) Facilitating the GTO.
C) Facilitating the primary (Ia) afferents, which in turn stimulate the extrafusal fibers of the muscle.
D) Inhibiting the secondary (II) afferents, which in turn stimulate the extrafusal fibers of the muscle.
