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.

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.
How would increased estrogen affect the river otter population?
