Principal Structures of the Brain
Let's dive into the fascinating world of brain anatomy! Understanding the location of key brain structures is crucial for comprehending how our nervous system functions and coordinates movement.
Major Brain Divisions
1. Cerebrum
The cerebrum is the largest and most prominent part of the brain, sitting at the top and divided into two hemispheres.
The cerebrum makes up about 85% of the brain's weight and is responsible for conscious thought, voluntary movement, and processing sensory information.
2. Cerebellum
Located at the back of the brain, underneath the cerebrum:
- Sometimes called the "little brain"
- Sits behind the brainstem
- Has a distinctive folded appearance
3. Brainstem
Positioned at the base of the brain, connecting to the spinal cord:
- Acts as the main communication highway
- Contains vital control centers
