Answers. Best Answer: I would say instinct is a largely inheritable and unalterable tendency of an organism to make a complex and specific response to environmental stimuli without involving reason. And your reflex is an automatic response to a stimulus not involving higher mental centers.
A reflex is a quick involuntary action. There are five steps to a reflex: the stimulus occurs, the sensory neurons sense the stimulus, it sends a message to your spinal cord (â¦ it doesn't reach the brain right then), the spinal cord sends a message to your motor neurons, and the reflex occurs.eflexes follow a Reflex ARC. The Arc is through the spinal cord. While the information gets sent to the brain (you know you touched something hot, or you are choking and coughing), the reflex totally by-passes the brain.
