WebA reflex action follows this general sequence and does not involve the conscious part of the brain, which makes it much quicker. The nerve pathway followed by a reflex action is called a reflex arc . WebA 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. The brain will receive the input while the ...

WebApr 28, 2024 · 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.”. There are four parts to a monosynaptic simple reflex. The first is a sensor, which ... WebSpinal reflexes were long considered hard wired, essentially unchanging input–output relationships. Work over the past 40 years has shown that the spinal reflex circuits are continually undergoing functional and structural changes that impact pain (nociception), locomotor patterns, sensory information control, and more.
