Illustration of the reflex arc.
A reflex is an involuntary and nearly instantaneous movement in response to a stimulus. The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse before that impulse reaches the brain.[1]
Relex arcs can be
- Monosynaptic ie contain only two neurons, a sensory and a motor neuron. Examples of monosynaptic reflex arcs in humans include the patellar reflex and the Achilles reflex.
- Polysynaptic ie multiple interneurons (also called relay neurons) that interface between the sensory and motor neurons in the reflex pathway.[2]
