6.Describe the difference between the midbrain and the hindbrain. (4 marks)
The hindbrain holds and contains the oldest parts of our brain as we grow. It receives signals from the spinal cord and sends the information received to another part of the brain. The midbrain is located between the hindbrain and the forebrain, and contains major structures just like the hindbrain, except the midbrain also contains important cell bodies. They both receive information and send it to another portion of the brain. There locations are different though, and the midbrain contains cells, whereas the hindbrain, contains the oldest parts of our brain as it grows.
7.In your own words, describe the difference between sensation and perception, and give one example that explains your understanding. (4 marks)
Sensation occurs when our sensory receptors become stimulated which therefor produces nerve impulses that the brain receives. The brain then turns these impulses into an image or sound, taste or smell, etc. This is how we are able to use our 5 senses. An example of this would be when your grandma bakes a fresh apple pie and you walk into her house. Immediately the smell hits you, and sends impulses to your brain, saying that something smells good and you want to eat it. Our nose would be sensory organ in this case.
Perception is the happening where the brain thought out, and organized neutral impulses. It is the brains reaction to a certain stimuli, in a more organized way.It is key in helping us make rational decisions and thought out choices. Related to physical stimuli and allows us to create emotion and memories. An example of this would be burning your hand on the stove. Once it happens and we feel the pain of getting burnt, our brain then gets the natural impulse to never do that again and creates a thoughtful decision. We then are hurt, which creates the emotional link to it, and will stay as a memory to know to never do again. It also links to sensation as well, because as we touch the stove, that is our physical sensation taking place.
