Answer:
salivating at the thought of a hamburger
Explanation:
The autonomic functions of the human body are governed by the autonomic nervous system, which is an involuntary system that transmits nerve impulses from the central nervous system to the periphery, stimulating peripheral organs and systems.
Salivating at the idea of a hamburger is an unconscious action, that is, we cannot control it; such as the heartbeat, breathing, among other actions of our human body.
