ANATOMY

Detailed explanation-1: -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-2: -A spinal reflex is an unconscious, involuntary and automatically occurring response to certain stimuli without any involvement of the brain. When a spinal reflex occurs, the spinal cord responds to the message directly, before the message is carried further on to the brain.

Detailed explanation-3: -The spinal cord transmits nerve impulses to and from the brain and mediates several important reflexes. It also coordinates more complex motor sequences (e.g. those required for walking).

Detailed explanation-4: -It is called a reflex action. Thus, Reflex action is an automatic, spontaneous and mechanical response to a stimulus controlled by spinal cord without the involvement of brain.
