Erin was riding a bicycle without a helmet and was struck by a car. She hit the back of her head very hard in the fall. The physician is quite concerned because the medulla oblongata is located at the base of the skull. She explained to her parents that injury to the medulla could result in which of the following: the loss of speech, amnesia (the loss of all memory), the loss of coordination so that the child may never again regain the motor skills needed to ride a bicycle, or, death because many life-support are controlled here?
