Question

Quizplus · Accepted Answer

Reciprocal innervation and recurrent collateral inhibition both involve the activation of an inhibitory interneuron to inhibit the activation of a muscle group. Isometric contraction does not involve the activation of inhibitory interneurons. Therefore, the correct answer is E, which includes both A and B as choices that require inhibitory interneurons.
