Yes, the brain does contain fluid. This fluid is called cerebrospinal fluid (CSF).
Cerebrospinal Fluid and the Brain
What is CSF?
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spinal cord.
Where is CSF found?
- CSF circulates in cavities deep within the brain called ventricles.
- It also bathes the brain and spinal column.
What does CSF do?
- CSF acts as a cushion, protecting the brain and spinal cord from injury.
- It also helps remove waste products from the brain.
What happens when there is too much CSF?
When there is an abnormal buildup of CSF, it can lead to a condition called hydrocephalus. As highlighted in the reference, “Hydrocephalus is the buildup of fluid in cavities called ventricles deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain.”
Key aspects of hydrocephalus:
- Fluid buildup: The primary characteristic of hydrocephalus is the accumulation of CSF in the brain's ventricles.
- Increased ventricular size: As the fluid accumulates, the ventricles enlarge.
- Pressure on the brain: This increase in fluid volume leads to pressure on the brain tissue.
In summary
So, while having fluid in the brain is normal and essential for brain function, an excessive buildup of this fluid leads to hydrocephalus.
