What Is the Choroid Plexus?

The choroid plexus is the anatomical structure of the brain. It is located in a certain part of the ventricle. The choroid and its vessels and the epithelial epithelium together form the choroid tissue. In some places, the vessels repeatedly branch into plexus, together with the pia mater and ventricles on the surface The epithelial epithelium bursts into the ventricle together to form the choroid plexus, which is the main structure for generating cerebrospinal fluid. The cerebrospinal fluid produced by the choroid plexus of the lateral ventricle flows to the third ventricle through the foromina of Monra, merges with the cerebrospinal fluid produced by the third ventricle, flows to the fourth ventricle through the midbrain water duct, and then with the fourth ventricle The cerebrospinal fluid generated by the choroid plexus flows into the cerebellar medullary cistern through the median foramen of the fourth ventricle and the lateral foramen of the fourth ventricle, and quickly spreads to the entire subarachnoid space, flows to the back of the brain, penetrates into the superior sagittal sinus through the arachnoid grains, Flow into the bloodstream.

Clinically, it is mainly used for the diagnosis of hydrocephalus, because excessive production of cerebrospinal fluid is one of the causes of hydrocephalus. Choroid plexus tumors rarely seen can also be the cause of cerebrospinal fluid excess.

Medical Terminology

In a certain part of the ventricle, the pia mater and the blood vessels above it form the choroidal tissue together with the epithelial epithelium. In some parts, the blood vessels repeatedly branch into plexuses. Together with the pia mater and the epithelial epithelium on the surface, they enter the ventricle to form the choroid plexus. The main structure that produces cerebrospinal fluid. In adults, about half a liter of cerebrospinal fluid can be produced every day. CSF is a clear, colorless, cell-free fluid that circulates in the subarachnoid space of the brain and spinal cord. ^[1]

The cerebrospinal fluid produced by the choroid plexus of the lateral ventricle flows to the third ventricle through the foromina of Monra, merges with the cerebrospinal fluid produced by the third ventricle, flows to the fourth ventricle through the midbrain water duct, and then with the fourth ventricle The cerebrospinal fluid generated by the choroid plexus flows into the cerebellar medullary cistern through the median foramen of the fourth ventricle and the lateral foramen of the fourth ventricle, and quickly spreads to the entire subarachnoid space, flows to the back of the brain, penetrates into the superior sagittal sinus through the arachnoid grains, Flow into the bloodstream.

Cerebrospinal fluid surrounds the brain and surrounds the brain upwards, and is reabsorbed through the arachnoid particles on the dura mater wall. ^[1]

Overproduction of cerebrospinal fluid is one of the causes of hydrocephalus. Choroid plexus tumors rarely seen can also be the cause of cerebrospinal fluid excess. ^[1]
