Meninges: The meninges are the protective membranous coverings

The meninges are the protective membranous coverings that surround the brain and spinal cord. They consist of three distinct layers: the dura mater, arachnoid mater, and pia mater. These layers serve two key functions: Provide a supportive framework for the cerebral vasculature. Work alongside cerebrospinal fluid (CSF) to cushion the central nervous system (CNS) and prevent mechanical injury. In this article, we will review the anatomy of the three meningeal layers and their clinical relevance. Meninges are the singular meninx. There are three membranous envelopes, which are called pia mater, arachnoid, and dura mater. These surround the spinal cord and brain. The cerebrospinal fluid fills the brain ventricles and the space between the arachnoid and the pia mater. The function of the meninges and of the cerebrospinal fluid is major to protect the central nervous system. Structure of Meninges Pia Mater The meningeal envelope that tightly adheres to the surface of the spinal cord and ... In anatomy, the meninges (/ məˈnɪndʒiːz /; [1][2] sg. meninx / ˈmiːnɪŋks, ˈmɛnɪŋks /; [3] from Ancient Greek μῆνιγξ (mêninx) 'membrane') [4] are the three membranes that envelop the brain and spinal cord. In mammals, the meninges are the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid is located in the subarachnoid space between the arachnoid mater and the pia mater. The primary function of the meninges is to protect the central nervous system. [5] This image provides a detailed cross-sectional view of the meninges , the protective layers surrounding the central nervous system (CNS), along with associated structures like the dura mater, arachnoid, and pia mater. It illustrates the anatomical relationship between the skin, bone, and meninges , highlighting their role in safeguarding the brain and spinal cord. Dive into this article to explore the intricate anatomy and physiological significance of these structures.
