explain the role of spinal cord in reflex arc

Asked by  | 19th Jun, 2008, 11:49: PM

Expert Answer:

Nerves from all over the body meet in a bundle in the spinal cord on their way to the brain.  Reflex arcs are formed 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. Reflex arcs are needed for quick responses.
