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)
Right hem: Frontal
judgement, planning and processing of new memories
Left hemisphere is responsible for…
language, rational, linear thinking, planning, controls right side of body, logic
The split in the brain is called what
Corpus Callosum
Injury or damage of the brain follows 2 facts…
1) Severed brain and spinal cord neurons do not regenerate
2) Some brain functions seem to be pre-assigned to specific areas
Plasticity of the brain
ability to change by reorganizing and building new pathways based on experiences
What is the endocrine system
Look at notes for definition
