Draw a labelled diagram of the human brain. Describe the jobs of its three main regions.

1. 1 · Define in one line. The brain is the main coordinating centre of the body; with the spinal cord it forms the central nervous system.
2. 2 · Forebrain. Main thinking part; areas for sight, hearing and smell; control of voluntary muscles; hunger centre.
3. 3 · Midbrain. With the hindbrain, controls many involuntary actions.
4. 4 · Hindbrain.
   • Pons: a part of the hindbrain; label it in the diagram.
   • Medulla: blood pressure, salivation, vomiting.
   • Cerebellum: posture, balance, precise movements.
5. 5 · Draw the brain. [Diagram: cerebrum, hypothalamus, pituitary gland, midbrain, pons, medulla, cerebellum, spinal cord]
6. 6 · Protection and daily life. The skull and the fluid around the brain protect it, and a helmet on a two-wheeler adds one more layer.
7. 7 · Close in one line. Each region has its own job, and together they control the whole body.

Scoring tip: Label the forebrain, midbrain and hindbrain as groups, then each part. Keep cerebrum and cerebellum clearly apart.
