A
  • the cerebellum
  • the pons
  • the medulla
17
Q
  1. What does the term “brainstem” refer to?
A
  • the midbrain, the pons and the medulla together
18
Q
  1. What is the Cerebrum?
    What is it in control of?
A
  • it is also known as the Cortex
  • it is the largest part of the human brain
  • it is associated with higher brain functions
    (thought, actions)
19
Q
  1. What is the Frontal lobe responsible for?
A
  • reasoning
  • planning
  • parts of speech
  • movements
  • emotions
  • problem solving
20
Q
  1. What is the Parietal lobe responsible for?
A
  • it controls movement
  • orientation
  • recognition
21
Q
  1. What is the Occipital lobe associated with?
A
  • visual perception
  • processing
22
Q
  1. What is the Temporal Lobe responsible for?
A
  • control perception
  • recognition of auditory stimuli
  • memory
  • speech
23
Q
  1. How does the wrinkly appearance of the cerebral cortex make the brain more efficient?
A
  • it increases the surface area of the brain
  • it increases the amount of neurons within it
24
Q
  1. Do the two hemispheres look symmetrical?
A
  • they look mostly symmetrical
  • each side functions slightly differently from the other
25
Q
  1. What does the right hemisphere focus on?
A
  • it focuses on the creativity
26
Q
  1. What does the left hemisphere focus on?
A
  • it is associated with logical abilities
27
Q
  1. What is the Corpus Callosum?
A
  • it is the bundle of axons
  • it connects the two hemispheres
28
Q
  1. What is the Cerebellum?
A
  • this is also known as the little brain
  • it is similar to the cerebrum because it has two
    hemispheres
  • it has a highly folded surface
  • this is called the Cortex
  • the structure helps with the regulation and the coordination of movement, posture and balance
29
Q
  1. What is the limbic system often referred as?
A
  • it is referred to as the emotional brain
  • it is found deep with the cerebrum
30
Q
  1. What does the limbic system contain?
A
  • the thalamus
  • the hypothalamus
  • the amygdala
  • the hippocampus
31
Q
  1. What is the thalamus?
A
  • it is a massive gray matter located in the forebrain
  • it acts as a centre for pain perception
32
Q
  1. What is the function of the hypothalamus?
A
  • it is to regulate homeostasis
  • to regulate emotion
  • to regulate thirst and hunger
  • it regulates the autonomic nervous system
33
Q
  1. What is the amygdala?
A
  • it is the part of the telencephalon
  • it is located in the temporal lobe
  • it is involved in memory, emotion and fear
34
Q
  1. What is the hippocampus?
A
  • this is the part of the brain that is important for learning
  • it is important for memory
  • it is important for converting short term memory to long term memory
35
Q
  1. What is found underneath the Limbic system?
A
  • the brain stem
36
Q
  1. What is the brain stem?
A
  • it is responsible for the basic vital life functions:
    - breathing
    - heart beat
    - blood pressure
37
Q
  1. Why is the brain stem considered the most simple part of the brain?
A
  • this is because the entire brain of animals
    (such as reptiles)
    resembles the brain stem
38
Q
  1. What is the mid brain responsible for?
A
  • vision
  • hearing
  • eye movement
  • body movement
39
Q
  1. What are the functions of the medulla oblongata and the pons?
A
  • they have the centres of the vital functions
    (these include breathing and heart beat)
