When pressure in the aorta sharply increases, the force and rate of cardiac contractions decrease. What nerve contains sensitive fibers from baroreceptors of the aortic arch?
- A. Recurrent laryngeal nerve
- B. Inferior cervical cardiac nerve (Pavlov’s nerve)
- C. Glossopharyngeal nerve
- D. Carotid sinus nerve (Hering’s nerve)
- E. Vagus nerve
