What process is associated with the movement or application of mental impulse?

The process associated with the movement or application of a mental impulse is best described as propulsion. In the context of chiropractic philosophy, mental impulse refers to the nervous system's communication and its role in the body’s functions. Propulsion signifies the directional movement or driving force behind an action, which aligns with how mental impulses are transmitted through the nerves to facilitate body functions.

In chiropractic practice, understanding how mental impulses travel and stimulate bodily functions is vital. It reflects the emphasis on the nervous system's capability to influence health and healing. This concept is foundational to chiropractic philosophy, denoting how vitalistic principles govern physiological processes.

While other terms might appear relevant, they do not capture the essence of movement or action as directly as propulsion does. This makes propulsion the most appropriate choice in this context, as it directly connects to the dynamic aspect of how mental impulses operate within the body.
