Choroid plexus of cerebral hemisphere: anatomy, location and function

The choroid plexus is a vascular, fringe-like tissue in the cerebral ventricles that produces cerebrospinal fluid. Its epithelium, a modified ependyma covering a capillary network, secretes cerebrospinal fluid and forms the blood-CSF barrier.

Choroid plexus of cerebral hemisphere at a glance

What it is
The choroid plexus is a vascular, fringe-like tissue in the cerebral ventricles that produces cerebrospinal fluid.
Location
In the cerebral hemispheres it lies in the body, atrium and temporal horn of each lateral ventricle, and is attached along the choroid fissure.
Function
Its epithelium, a modified ependyma covering a capillary network, secretes cerebrospinal fluid and forms the blood-CSF barrier.
Body system
Nervous · single, midline structure
FMA ID
FMA61934 (Foundational Model of Anatomy)

Key facts

  • Total CSF production is roughly 500 mL per day.
  • Blood supply comes from the anterior choroidal artery (from the internal carotid) and the posterior choroidal arteries (from the posterior cerebral).
  • Not present in the frontal or occipital horns.
