Role of spinal cord in reflex action

Web18 Feb 2024 · Reflexes are faster than our normal reactions because reflex actions use a different neural pathway. Unlike normal movement, most reflexes bypass the brain, receiving signals only from the spinal cord. Every one of us has burned our hand from touching a hot object, or has been zapped when touching an open electrical socket. Web5 Jan 2024 · What is the role of spinal cord in reflex action? A 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.
