Well they are both used in the Autonomic system and Somatic system. Acetylcholine is the neurochemical which stimulates muscles. (I assume you mean NA=Sodium?) when the Acetylcholine binds with the muscle it causes sodium to diffuse in to the cell and potassium to diffuse out, causing depolarization and an Action Potential to be formed. This ultimately causes the muscle to move.
By release of chemical neurotransmitters like epinephrine and norepinephrine, increasing response to tough external stimuli.

The autonomic nervous system.
Autonomic nervous system is one of the two subdivisions of the nervous system; the other being the somatic nervous system. The autonomic nervous system regulates and controls bodily functions and processes without conscious control or voluntary input (e.g. pumping blood around your body or digesting food). It is further subdivided into the sympathetic and parasympathetic systems; categorized by the neurotransmitters utilized and the physiological functions.Sympathetic = "fight or flight"Parasympathetic = "rest & digest" systemBoth are part of the autonomic nervous system.Longer than a sentence but I'm sure you cut it down somehow!
The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous systems.
The involuntary nervous system that is involved with organ regulation is called the Autonomic nervous system (ANS) and is comprised of the Sympathetic nervous system and the Parasympathetic nervous system.
Dysfunction of the autonomic nervous system (ANS) is known as dysautonomia. The autonomic nervous system regulates unconscious body functions.
The autonomic nervous system is responsible for the control of the functions of the internal organs and it has two divisions. These are the sympathetic nervous system and the parasympathetic nervous system.
The autonomic nervous system functions independently and continuously without conscious effort.
