An autonomic nervous-system chart can summarize functions such as heart-rate and digestive regulation. It should not assign an emotional state to a pulse or imply that sympathetic and parasympathetic activity are simple on-off switches.
A function chart, with its limits
The sympathetic and parasympathetic systems are the two major divisions described in MSD’s overview. The autonomic system contributes to functions including heart rate, blood pressure, sweating, and digestion. These are physiological functions, not emotional labels. [ANATOMY]
| Chart entry | What it represents | What it does not show |
|---|---|---|
| Sympathetic division | One major autonomic division | A person’s moral or emotional state |
| Parasympathetic division | The other major autonomic division | An always-good or permanently-on state |
| Heart rate | A regulated physiological function | A diagnosis from one reading |
| Digestion | Another autonomically regulated function | The cause of one digestive symptom |
This original chart summarizes the source. It is not a measurement instrument or a treatment plan.

A worked situation: Heart-rate regulation
Fictional example. A learner uses a comparison chart to understand terms. The chart is not used to decide that a tired afternoon proves a shutdown state or that a breathing exercise changes a measured autonomic diagnosis.
