Detailed explanation-1: -Overview over the basic anatomy and functions of the vagus 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 (17).

Detailed explanation-2: -Eye movements can increase blood flow to the vertebral artery and stimulate the vagus nerve as it passes through the upper neck. Relaxing the muscles in the eyes engages an innate reflex called the oculocardiac reflex (OCR) which initiates a parasympathetic response to slow down the heart rate and lower blood pressure.

Detailed explanation-3: -The vagus nerve serves as the body’s superhighway, carrying information between the brain and the internal organs and controlling the body’s response in times of rest and relaxation.
