Web28. apr 2024 · There are many different types of reflexes, but the most basic is called a simple reflex. A simple reflex contains only one space where information in the spinal cord travels between two nerve cells, called neurons. The space between two neurons is called a synapse. Thus, a simple reflex is called monosynaptic, where “mono” means “one.”.
