The choroid plexus, or plica choroidea, is a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain. [1] Regions of the choroid plexus produce and secrete most of the cerebrospinal fluid (CSF) of the central nervous system .
The tela choroidea (or tela chorioidea) is a region of meningeal pia mater that adheres to the underlying ependyma, and gives rise to the choroid plexus in each of the brain’s four ventricles. [ 1 ] [ 2 ] Tela is Latin for woven and is used to describe a web-like membrane or layer. [ 3 ]
The majority of the CSF is formed in the choroid plexus and flows through the brain along a distinct pathway: moving through the cerebral ventricular system, into the subarachnoid space surrounding the brain, then draining into the systemic blood column via arachnoid granulations of the dural sinuses or to peripheral lymphatics along cranial ...
[1] [2] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, [3] allowing for the flow of CSF to circulate. [3] [4]
Most (about two-thirds to 80%) of CSF is produced by the choroid plexus. [1] [2] The choroid plexus is a network of blood vessels present within sections of the four ventricles of the brain. It is present throughout the ventricular system except for the cerebral aqueduct, and the frontal and occipital horns of the lateral ventricles. [21]
The anterior choroidal artery typically originates from the internal carotid artery.It may (rarely) instead arise from the middle cerebral artery. [1]It originates from the distal internal carotid artery (ICA) 5 mm distal to the origin of the posterior communicating artery and just proximal to the terminal bifurcation of the ICA.
The plexus is the characteristic form of nervous system in the coelenterates and persists with modifications in the flatworms.The nerves of the radially symmetric echinoderms also take this form, where a plexus underlies the ectoderm of these animals and deeper in the body other nerve cells form plexuses of limited extent.
