Study Notes

Cerebrum

Occupies over 80% of the brain's space
Contains over 10 billion neurons
Folds increase its surface area threefold
Responsible for higher intellectual functions, conscious thoughts, and intentional movement of body parts
Receives sensory messages from all body parts
Divided into two parts: right and left cerebral hemispheres
Right hemisphere controls the left side of the body, while the left hemisphere controls the right side
Each hemisphere can work independently, but both are used for most activities
One side usually dominates in a particular task
Left hemisphere: dominant in language and logical thinking (e.g., mathematical ability)
Right hemisphere: more creative and emotional, responsible for musical and artistic abilities

Cerebellum

Located at the base of the cerebrum, where the skull curves inwards
Responsible for coordination and balance
Essential for walking and other physical activities
