Ia vs Ib Reflex Arcs

Compare the two spinal reflex pathways: Ia from the muscle spindle goes straight to an alpha motor neuron and makes the muscle contract, while Ib from the Golgi tendon organ first uses an inhibitory interneuron and makes the muscle relax. Click the pathway buttons or any labeled node to isolate a route and read its role; use the quiz buttons for the disynaptic reflex.
