Reflex arc in spinal cord
Web3.The Nervous System • Both the brain and the spinal cord: • Receive sensory input from receptors • Contain reflex centers • Send motor output to effectors • Reflex • Rapid, … 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.
