TOPIC 2: Brain structure Flashcards
Brain is broken down into how many components?
3
Component 1 of brain -Hindbrain
Most primitive part of brain and is protected by thickest part of the cell and includes things that keep us alive
Hindbrain includes CEREBELLUM…
movement, balance, how much time past, non-verbal learning
Hindbrain includes MEDULLA…
breathing and circulation
Hindbrain includes PONS….
Sleep, movement
Component 2 of brain: Midbrain
Includes RETICULAR FORMATION and important for sleep, attention, and arousal. if damaged, in coma.
Component 3 of brain: Forebrain
Includes limbic system, amygdala, hippocampus (where new memories are formed)
-in charge of controlling emotion, motivation, and pleasure centers
What is the hippocampus in charge of?
New memories are formed
forebrain includes thalamus which is….
handles incoming and outgoing information
forebrain inclused hypothalamus which…
controls basic needs; hunger, thirst, body temp, sexual behavior
forebrain includes cerebrum which is…
covered by tissue -cervral cortex allows problem solving.
the cerebrum is divided down the middle by a deep fissure which creates 2 hemispheres (left and right)
What does the right hemisphere control?
left side of body and vise versa for the left
Right hemisphere: Occipital
for vision signals sent and processed
Right hemisphere: Temporal
Auditory signals are sent and processed
Right Hem: Pariental
Sense of touch, mathematical and spacial reasoning
-monitors body position (if eyes are closed, for example)
