It has two main components: an epithelium and blood capillaries<br \/>\nIts epithelium is a single layer of specialized cuboidal epithelial cells (choroid epitheliocytes) that cover a rich network of fenestrated capillaries. The choroid epitheliocytes produce and secrete into the ventricles of the brain the cerebrospinal fluid (CSF) that occupies also the subarachnoid space and cavities of the spinal cord.<br \/>\nThe epithelium and its underlying tissue are folded into numerous villi, an arrangement that increases the production of CSF. It was already shown in the chapter on Epithelial Tissue as an example of a simple cuboidal epithelium <a href=\"https:\/\/mol-en.icb.usp.br\/index.php\/2-8-covering-epithelia\/\">Click to review the epithelium.<\/a><br \/>\nThe image is of a small region of the choroid plexus placed on the surface of the cerebellum, that is the organ seen at the left of the choroid plexus.<br \/>\nHover your cursor over the image or click over the image to identify the choroid plexus, highlighted in orange.<\/p>\n<div onclick>\n<div class=\"image-container\">\n<div class=\"extra\">\n<a href=\"javascript:void(0)\"><img decoding=\"async\" src=\" https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/9-22.jpg \" onmouseover=\"this.src=' https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/9-22-MO.jpg'\" onmouseout=\"this.src=' https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/9-22.jpg'\" \/><\/a><\/div>\n<p>Choroid plexus.
