What is the function of arachnoid?
In this membrane, there are protrusions due to the expansion of the racoid that perforate the dura mater, receiving the name of villi. These properties have the function of transferring the cerebrospinal fluid to the blood.
The arachnoid is one of the three meninges, the protective membranes that cover the brain and spinal cord. The arachnoid is a derivative of the neural crest mesectoderm of the embryo.
