• A. Medulla oblongata
• B. Medulla oblongata and cerebrum
• C. Medulla oblongata and cerebellum
• D. Cerebellum

Answer 1

The correct option is A Medulla oblongata

• Medulla oblongata extends from the Pons Varolii above and is continuous with the spinal cord below.
• Medulla oblongata receives and integrates signals from the spinal cord and sends resulting signals to the cerebellum and thalamus.
• It contains centres that regulate heart rate, blood pressure, breathing, salivation, sneezing, vomiting and coughing.

Thus, the correct answer is 'Medulla oblongata'.
