Is the Knee Jerk Reflex Polysynaptic

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.

Is the knee-jerk reflex Monosynaptic or Polysynaptic?

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.

What are Polysynaptic reflexes?

Any reflex with more than one synapse (1), not counting the synapse between neuron and muscle, and hence involving one or more interneurons. In humans, all reflexes except stretch reflexes are polysynaptic.
