Textbook Question
Chapter 19, Problem 5CAL
During surgery, the right vagus nerve was accidently cut. Explain the effect to the heart rate.
- a. There is no change to the heart rate because the vagus nerve does not innervate the heart.
- b. The heart rate increases to the inherent rhythm of SA nodal cells.
- c. The heart stops beating, and heart rate becomes zero.
- d. The heart rate decreases to the inherent rhythm of SA nodal cells.
