Question 1

After stretching an intrafusal fiber, the next event is
◦ a decrease in muscle tone.
◦ an increase in action potentials along the associated sensory neuron.
◦ a decrease in muscle tension.
◦ decreased sensitivity to stretching.
◦ All of the answers are correct.

Question 2

When there is a resistance to stretch produced by a given limb muscle,
◦ intrafusal fibers receive fewer action potentials from the gamma motor neurons.
◦ gamma motor neurons are inhibited by higher brain centers.
◦ the muscle involved in the movement immediately shortens when stimulated.
◦ there is a decrease in the amount of force generated by extrafusal muscle fibers.
◦ muscle tone is increased and more motor units are recruited to the contraction.
