Answer to Question 1

Parasympathetic (inhibitory) nerve fibers supply the sinoatrial node, atrial muscle, and the atrioventricular junction of the heart by the vagus nerves.

Answer to Question 2

D
Enlargement of the atrial chambers, ventricular chambers, or both, may occur if there is a volume or pressure overload in the heart. Dilatation is an increase in the diameter of a chamber of the heart caused by volume overload. Dilatation may be acute or chronic. Hypertrophy is an increase in the thickness of a heart chamber because of chronic pressure overload. Hypertrophy is commonly accompanied by dilatation. Enlargement is a term that implies the presence of dilatation or hypertrophy or both.
