Biology Hacked: The Brain Summarized

Biology Summary:The Brain

In years 7,8,9 or 10? Here is a high-school level summary on the composition and function of the main features in the brain. Includes functions of the cerebrum, cerebellum, brainstem/medulla, midbrain and corpus callosum summarised. 

The Cerebrum (80% of the brain)

·        Folded to increase surface area by approximately 3 times

·        Higher intellectual functions

·        Controls

o   Conscious thoughts

o   Voluntary movement

o   Sensory messages

·        Right (creativity and emotion) and left(language and maths) hemispheres

The Cerebellum

·        Fine tunes and coordinates movement and balance

·        Pons relay messages from cerebrum to cerebellum to spinal chord

The Brain Stem/medulla

·        Regulates vital functions (breathing, blood pressure and heart rate)

Midbrain

·        Allows the two sides of the brain to communicate.

Corpus Callosum

·        Joins two hemispheres of the brain.
