Web"A reflex arc is a neural pathway that controls an action reflex. Most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the …
WebA reflex arc is a neural pathway that controls a reflex.In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
