ANATOMY

Detailed explanation-1: -Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons.

Detailed explanation-2: -Spinal reflexes are rapid, involuntary, and predictable responses to specific stimuli that are mediated by the spinal cord without requiring input from the brain. They occur as automatic, involuntary responses to stimuli generated within the nervous system.

Detailed explanation-3: -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.
