The Brain

• What is the primary function of the brain?

  It controls and coordinates everything you do.
• What is the composition of the brain?

  The brain is made up of billions of interconnected neurones.
• What are the main functions of the cerebrum?

  • Learning
  • Intelligence
  • Memory
  • Language
• What is the role of the hypothalamus?

  It maintains body temperature and produces important hormones.
• What does the medulla control?

  It controls primary actions such as breathing and heartbeat.
• What is the function of the cerebellum?

  It is responsible for muscle coordination.
• Why is studying the brain important?

  It helps scientists understand brain functions and treat brain damage or disease.
• What is a limitation of using case studies to learn about the brain?

  They may not provide clear information about the functions of damaged brain areas.
• How can damage to the brain affect speech?

  Damage may impair speech, indicating that the affected area is related to speech functions.
• What is a challenge when using MRI scanners to study brain function?

  It cannot be known for sure if the same brain activity pattern occurs in normal situations.
• What are some issues with treating brain problems?

  It can be difficult to repair damage and access certain areas of the nervous system.
• Why is it hard to repair damage to the nervous system?

  Neurones in the CNS do not readily repair themselves.
• What is a potential risk of surgery to remove a brain tumour?

  It may lead to permanent damage to surrounding brain areas.
• What are the ethical considerations in studying brain function?

  • Informed consent may not be possible for seriously brain-damaged individuals.
  • Research relies on brain donations from deceased individuals.
  • Interpretation of case study results can be problematic.
• What is one way scientists learn about brain function from deceased individuals?

  By examining the brains of people who have died.
• What is the main focus of the study material?

  The functions and complexities of the brain.
• What is the total number of marks for the question about the functions of the hypothalamus, medulla, and cerebellum?

  3 marks
