Reflex arcs that contain only two neurons, a sensory and a motor neuron, are considered monosynaptic. ... Most reflex arcs are polysynaptic, meaning multiple interneurons (also called relay neurons) interface between the sensory and motor neurons in the reflex pathway.

What is the Polysynaptic pathway?

As the pathway of this reflex system is polysynaptic, it allows the integration of inputs from muscle, joint, and cutaneous afferents, and convergence with commands from supraspinal centers to common spinal interneurons. ... A polysynaptic pathway also mediates the effects of flexor-reflex afferent (FRA) fibers.

What is Polysynaptic reflex example?

For example, stimulation of pain receptors in the skin initiates a withdrawal reflex, which involves several synapses with several motor neurons and results in the removal of the organism or part from the stimulus. ...
