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.
sympathetic
They are controlled by the autonomous nervous system.== ==

An antagonist in the autonomic nervous system is a substance that blocks the action of neurotransmitters at specific receptors. This can result in the inhibition of certain physiological responses mediated by the autonomic nervous system, such as heart rate or smooth muscle contraction. Antagonists are often used in medicine to treat conditions where modulating autonomic functions is beneficial.
The autonomic nervous system controls involuntary bodily functions such as heart rate, digestion, and breathing. It consists of two main branches: the sympathetic nervous system, which activates the fight-or-flight response, and the parasympathetic nervous system, which promotes rest and relaxation. These two branches work in opposition to maintain homeostasis in the body.
The autonomic nervous system.
The autonomic nervous system that increases heart rate is the sympathetic nervous system. When activated, it releases neurotransmitters like norepinephrine, which stimulate the heart to beat faster and with greater force. This response is part of the body's "fight or flight" mechanism, preparing it for quick action. In contrast, the parasympathetic nervous system works to decrease heart rate.
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.
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.
