The impulse-based model of movement is a theory that explains how our muscles contract to generate a specific movement. The central idea is that an impulse must be generated in order for the muscle to contract and produce any kind of action, whether it’s voluntary or reflexive. This article will discuss the basic components of this theory and how they apply to human physiology.

This theory explains muscle contraction as an all-or-nothing process. The muscles contract, or they don’t. In order to generate that impulse there must be a difference between the excitatory and inhibitory signals in your nervous system. When those two signals are approximately equal, you’ll find that nothing happens because no one signal has enough power over the other to move on its own. So what’s happening when we talk about how nerves work? Well, it turns out that our nerve cells have two ways of transmitting messages: by sending chemical messengers called neurotransmitters and through electrical impulses called action potentials (AP). When these receptors receive information from outside stimuli such as pain or heat, they relay this message using an AP which
