MCAT Question of the Day
    •

    Q:

    		 During a heart transplant, the Vagus nerve is severed, eliminating parasympathetic control. Assuming nerve regrowth does not occur, what impact would Vagus nerve severance have on the heart?
    		 

    A

    		 Adrenaline would be unable to increase the heart rate.

    B

    		 The heart would be unable to beat without an artificial electrical stimulus.

    C

    		 In a transplant patient at rest, the heart would beat faster than it would in a non-transplant patient at rest.

    D

    		 The heart would have difficulty properly timing atrial and ventricular contractions.
