There are two pathways by which the Jendrassik maneuver facilitates alpha motor neuron output. Describe one.
Succinylcholine act as adepolarising agent that prevents repolarization of the somatic motor neuron. Thus, no further ACh is released until drug is cleared. Name another site within the MNJ we could target to prevent muscle contraction, and explain why this would work.
Describe the functions of gamma motor neurons and explain why they are stimulated at the same time as alpha motor neurons during voluntary muscle contractions.
