The main parts of the brain and spinal cord are important for how our bodies work. Let’s break it down!

Brain Parts

• Cerebrum: This is the biggest part of the brain. It makes up about 85% of the brain's weight.

• Cerebellum: This part helps with coordination, which means it helps us move smoothly. It has more than 50% of the brain's nerve cells.

• Brainstem: This is made up of three parts: the midbrain, pons, and medulla. The brainstem is really important because it controls things we do automatically, like breathing.

Spinal Cord Parts

• Segments: The spinal cord is divided into 31 segments. These include:
  • 8 cervical segments (in the neck),
  • 12 thoracic segments (in the upper back),
  • 5 lumbar segments (in the lower back),
  • 5 sacral segments (in the pelvis),
  • 1 coccygeal segment (the tailbone area).
• Conus Medullaris: This is where the spinal cord ends. In adults, it usually stops around the L1-L2 vertebrae. The spinal cord is about 45 cm long in men and about 43 cm in women.

Understanding these parts is important because they help us know how the brain and spinal cord work together to keep our bodies functioning!
