A Polysynaptic Reflex refers to a type of reflex involving multiple neurons and synapses in the spinal cord. It is characterized by a more complex neural pathway compared to a monosynaptic reflex. AI generated definition based on: Progress in Neurobiology , 2001

Polysynaptic spinal reflexes produce functionally useful compensatory responses during locomotion, which are more complex than simple stretch-reflex responses.

May 22, 2019 · Monosynaptic reflexes include, for example, the biceps and triceps reflexes, and patellar stretch reflex or knee jerk (see figure below). In contrast, polysynaptic reflexes are mediated through at least two synapses and one interneuron.

Jan 3, 2023 · The withdrawal reflex can occur in either the upper or lower limbs and is a polysynaptic reflex, which means that interneurons mediate the reflex between the afferent (sensory) and efferent (motor) signals.

All other reflexes have undefined neural pathways. They are assumed to involve more than 2–3 central synapses and are called polysynaptic. These reflexes typically show longer delays between the stimulus and the response, they can be both phasic and tonic.

Jan 11, 2025 · Monosynaptic and polysynaptic reflexes are two distinct types of neural pathways that mediate rapid, automatic responses to stimuli. Monosynaptic reflexes involve only a single synapse between a sensory neuron and a motor neuron, creating a direct and rapid response.

Unlike monosynaptic reflexes, which have a direct connection between a sensory and motor neuron, polysynaptic reflexes allow for more complex responses to stimuli and often involve the integration of information from various sources within the central nervous system.

polysynaptic reflexes - Lots of different pathways to the same motor neuron - Some are shorter and some are longer, but all of them try to get to the same motor neuron

Examples of monosynaptic reflex arcs in humans include the patellar reflex and the Achilles reflex. Most reflex arcs are polysynaptic, meaning multiple interneurons (also called relay neurons) interface between the sensory and motor neurons in the reflex pathway.

Nov 3, 2023 · Polysynaptic reflexes. Contrary to monosynaptic reflexes, polysynaptic reflexes are accomplished with the participation of one or more interneurons, meaning that the communication between the afferent and efferent neurons is indirect.
