What are the characteristics of the choroid plexuses?
The choroid plexus is a vascular convolute, consisting of epithelial cells (a type of microglia), fenestrated blood vessels, and stroma, which lie in the ventricular system of the brain. It is the main source of cerebrospinal fluid (CSF) and actively regulates the constituents in CSF.
Where is the choroid plexus located and what is its function?
brain ventricles
The choroid plexus (ChP) is a secretory tissue found in each of the brain ventricles, the main function of which is to produce cerebrospinal fluid (CSF).
What does the choroid plexus look like?
CSF is produced and secreted by the regions of the choroid plexus. The choroid plexus consists of modified ependymal cells surrounding a core of capillaries and loose connective tissue….

What is the choroid plexus and what does it secrete?
The choroid plexus is a complex tissue configuration made up of epithelial cells, capillaries (tiny blood vessels), and connective tissue that lines the ventricles of the brain. Its function first and foremost is to secrete cerebrospinal fluid (CSF), a clear fluid that protects the brain and spinal cord.
Why is the choroid plexus important?
The choroid plexus serves two roles for the body: it produces cerebrospinal fluid and provides a toxin barrier to the brain and other central nervous system tissue. The choroid plexus and the cerebrospinal fluid that it produces are necessary for proper brain development and central nervous system function.
What is the choroid plexus responsible for?
CSF
It is well known that the choroid plexus produces and secretes many biologically active neurotrophic factors into the CSF, being responsible for at least two-thirds of the CSF that travels between the spinal cord and brain, providing nutrients and removing waste.
What is the importance of the choroid plexus?
One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain. Secondly, the choroid plexus serves as a barrier in the brain separating the blood from the CSF, known as the blood-CSF barrier.
How does the choroid plexus work?
The choroid plexus is a network of capillaries and specialized ependymal cells found in the cerebral ventricles of the brain. The choroid plexus serves two roles for the body: it produces cerebrospinal fluid and provides a toxin barrier to the brain and other central nervous system tissue.
What causes choroid plexus?
A choroid plexus cyst happens when a small amount of the cerebrospinal fluid gets trapped in the layer of cells as your baby’s brain grows and develops. The cysts go away on their own during pregnancy, usually by week 32. Choroid plexus cysts can happen in any pregnancy.
How is choroid plexus formed?
These ventricles are lined by a specialized type of glial cell called ependymal cells, or the ependyma. The choroid plexus is formed by these vascularized invaginations, bordered by the ependyma.
What is the difference between tela choroidea and choroid plexus?
In the third ventricle the tela choroidea forms the roof of the ventricle. Two vascular fringes from the lower fold invaginate the roof and form the choroid plexus. The anterior layer of the fold, contains vascular fringes which make up the choroid plexus.
What does plexus choroideus mean?
choroid plexus, plexus choroideus (noun) a vascular plexus of the cerebral ventricles that regulate intraventricular pressure How to pronounce plexus choroideus?
What is the meaning of ‘choroid’?
medical Definition of choroid. : a vascular membrane containing large branched pigment cells that lies between the retina and the sclera of the eye — called also choroid coat.
What is choroid disease?
The range of diseases and disorders in the choroid include both inflammatory diseases and disorders. Diseases: • Chorioretinitis – (sometimes called choroid retinitis) – an inflammation of both the choroid AND the retina. It can also be classified according to causal diseases such as syphilis and tuberculosis.
