Meninges three membranous envelopes pia mater arachnoid and dura mater that surround the brain and spinal cord.
It is one of the few structures of the. Cerebrospinal fluid fills the ventricles of the brain and the space between the pia mater and the arachnoid. Provide a supportive framework for the cerebral and cranial vasculature. They are a set of membranes that cover both the spinal cord and the brain whose main function is to protect them from certain attacks.
The three meninges are the dura mater the arachnoid mater and the pia mater. The outermost membrane this is the thickest of the three layers and has both an outer and inner layer. The space between the two layers the subarachnoid space is filled with cerebrospinal fluid csf. You ll also learn about meningitis and why it is such a dangerous pathology.
