Meninges: The meninges protect the brain

The meninges protect the brain with three layers: dura mater, arachnoid mater, and pia mater. Meningitis is a serious condition causing inflammation of the meninges due to infections. Hematomas involve blood collecting in the brain, often between the dura and skull or dura and arachnoid. 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] The brain and spinal cord are enveloped within three layers of membrane collectively known as the meninges , with the cranial meninges specifically referring to the section that covers the brain. From superficial to deep, the three layers are the dura, arachnoid, and pia—the term “mater,” Latin for mother, often follows these names (i.e., dura mater, arachnoid mater, pia mater).[1] The dura, Latin for “hard,” is composed of dense connective tissue and adheres to the inner surface of ...
