1
Identify the primary functions of each brain region listed in the options: Cerebrum, Cerebellum, Hypothalamus, Pituitary, and Medulla oblongata.
Understand that the Medulla oblongata is responsible for regulating vital functions such as breathing, heart rate, and blood pressure.
Recognize that an injury to the Medulla oblongata can directly affect the ability to breathe, as it controls the autonomic functions necessary for respiration.
