PARTS:

 

The Cerebrum

• lgest and most developed part: what makes human separate from animals

• has 2 hemispheres separated with different jobs connected by a small bridge called the corpus callosum

 

Celebral Cortex 

• Cerebrum surafce layer, divided into 4 major regions:

  • FRONTAL LOBE

    • Intellectual activities + personality

    • Control voluntary muscle movement

  • PARIETAL LOBE

    • Touch and temperature awarness

    • Emotions and interpret speech

  • TEMPORAL LOBE

    • Vision and hearing

    • Link to memory and sensory info interpretation

  • OCCIPITAL LOBE

    • Vision

    • Interpret visual info

 

The Hindbrain

1. CEREBELLUM controls limb movement, balance + muscle control

 

2. PONS=relay stations sending messages between cerebellum + medulla oblongata

 

3. MEDULLA OBLONGATA=Autonomic nerve control centre (ex. breathing and heart rate, blood vessel diameter)

 

Thalamus and Basal Nuclei

• Thalamus is the brain region interpreting sensory info and signalling cerebrum

• Basal Nuclei is grey matter centres surrounding thalamus 

 

Left and Right Brain

• LEFT: verbal and math

• RIGHT: intuititive, spacial, artistic and musical
