Brain, Meninges & CSF Anatomy
Choroid plexus
The choroid plexus is tissue within the ventricles that produces cerebrospinal fluid.
In short: Choroid plexus
- It makes the CSF that fills the ventricles.
- It is located inside the brain's ventricles.
- Its activity relates to CSF balance.
- It is part of the brain's fluid-production system.
What it is
It is the CSF-producing tissue located within the ventricles, especially the lateral ventricles. It generates the fluid that fills and circulates through the brain's fluid system.
Understanding Choroid plexus
Because it produces CSF, the choroid plexus is part of the fluid balance that, when disrupted, can lead to hydrocephalus. The balance between CSF production and absorption keeps pressure normal; problems with circulation or absorption can cause fluid to build up.
Why it matters
Understanding the choroid plexus helps families see where CSF comes from and how an imbalance between production and absorption can contribute to hydrocephalus.
Common questions
What does the choroid plexus do?
Produces cerebrospinal fluid.
Where is it?
Inside the brain's ventricles.
How does it relate to hydrocephalus?
It is part of the CSF balance that can be disrupted.
Bottom line
The choroid plexus produces cerebrospinal fluid within the ventricles.
