Medulla regulates vital autonomic functions like breathing

Steps:

• Recall the medulla oblongata's role in the brainstem for involuntary processes.
• Identify options related to basic survival functions versus higher cognition.
• Match diaphragm control to respiratory regulation by the medulla.
• Eliminate options tied to other brain regions.

Why B is correct:

• The medulla controls autonomic breathing via the respiratory center, which signals diaphragm contractions for inhalation, as defined in neuroanatomy.

Why the others are wrong:

• A: Balance and coordination are functions of the cerebellum.
• C: Reasoning and thinking occur in the cerebral cortex.
• D: Hormone secretion is primarily handled by the hypothalamus and pituitary gland.

Final answer: B
