Quiz Over The Brain And Nervous System

Test on the components of the nervous system and the brain. Tests knowlege of hormonal controls and the stimulus-response model.


Questions and Answers
  • 1.

  • 2. 
    Imagine a dog running out onto the road in front of a vehicle.  Name three things which could influence the reaction time of the driver (the time between the dog running out and the driver putting his/her foot on the car brake).  (3 marks)

    There are theories that state that birth order has a part to play in forming a person's personality- particularly if a child is born first in the family as opposed to those who are born later. First-born sibblings are often more conscientious and seek parental approval, whilst later born sibblings are often more laid-back and can be better negotiators.  What do you think about this theory? There is no right or wrong answer to this question but you will be marked on the way that you support your argument with reasons and examples.

  • 7. 
    When a person faces a serious threat, the hormone adrenaline is released.  Name five things that occur (in the brain and/or the body) in response to the release of this hormone.  Give a reason why each of these responses may be helpful in an emergency. (5 marks)

    A man was stranded in a life raft at sea for a long period of time. The only food he had to eat was the fish he caught. Initially the man ate the fish flesh to survive, but did not eat the other parts as they tasted disgusting to him. As time went on, however he started to seek out the fish organs and eyes, which became tastier to him than the flesh. As it happens the organs and eyes are high in vital vitamins and minerals which are lacking in the fish flesh. What can this story tell us about the functioning of the brain? (2 marks)
  • 9.
