Question

What is vaga nerve?​

Answer 1

The word “vagus” means wandering in Latin. This is a very appropriate name, as the vagus nerve is the longest cranial nerve.

The vagus nerve is responsible for the regulation of internal organ functions, such as digestion, heart rate, and respiratory rate, as well as vasomotor activity, and certain reflex actions, such as coughing, sneezing, swallowing, and vomiting.
