Plexus autonomici refers to the network of neurons that regulate involuntary bodily functions, and there are several synonyms that are often used to describe this anatomical structure. One common alternative term is the autonomic nervous system, which encompasses all the nerves and ganglia involved in automatic bodily processes, such as digestion, heart rate, and breathing. Other synonyms for plexus autonomici include the parasympathetic nervous system, which is responsible for rest and digestion, and the sympathetic nervous system, which is associated with the body's fight-or-flight response. Additionally, some researchers also refer to plexus autonomici as the visceral nervous system, as it controls the functioning of internal organs.
