Question

The cranial nerves in humans that send parasympathetic stimulation to, among other organs, the heart, stomach, and liver are

• A. Vagus nerves
• B. Abducens nerves
• C. Trigeminal nerves
• D. Glossopharyngeal nerves

Answer 1

Answer: (A)

Vagus nerves

The parasympathetic nervous system decreases respiration and heart rate and increases digestion. Stimulation of the parasympathetic nervous systems results in the construction of pupils. Decrease heart rate and blood pressure.

The conduction of these responses are sent through cranial nerves called the vagus nerves.

So, the correct option is 'Vagus nerves'.
