autonomic
Beyond conscious control
Autonomic describes functions of the nervous system that operate without conscious control—heartbeat, digestion, breathing, pupil dilation.
The autonomic nervous system regulates these involuntary processes automatically: The drug affects autonomic responses.
By extension, autonomic can describe any process that runs on its own without deliberate intervention.
