Based on the Neurophysiological Properties of the Contractile Components of Muscle

question 10

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.
