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
