I know that the pathway of nerve impulses during a reflex action is called a reflex arc. However, I want to know whether the term reflex arc can be called either a reflex path or simple reflex?
A reflex arc is sometimes called the reflex pathway. While there is no involvement of the brain in the output/response to stimulus, it does receive signals via the spinal cord informing it of the action. In other words, the reflex action is registered in the brain as soon as it occurs.
