Explanation
- Examiners expect all three parts of the hind-brain named for full credit (1 mark), and the specific part — medulla — identified for the second mark.
- The textbook explicitly states: "All these involuntary actions including blood pressure, salivation and vomiting are controlled by the medulla in the hind-brain." Use this exact terminology.
- Do not confuse cerebellum (precision of voluntary actions / balance) with medulla (involuntary actions).
