The central nervous system comprises the brain and spinal cord. The brain assumes a focal part in the control of most substantial capacities, including mindfulness, developments, sensations, contemplations, speech, and memory. Some reflex movements can happen by means of spinal cord pathways without the investment of brain parts. Meninges consists of three layers encompassing the brain and spinal cord. The external layer, the dura mater, is strong, white stringy connective tissue. The center layer of meninges is arachnoid, a thin layer looking like a spider web with various threadlike strands connecting it to the deepest layer. The space under the arachnoid, the subarachnoid space, is loaded up with cerebrospinal liquid and contains veins. The pia mater is the deepest layer of meninges. This narrow, fragile layer is firmly bound to the outside of the brain and spinal cord and can't be separated away without harming the surface.The correct order of the layers of the meninges from central nervous system to the outside are as follows: 1st- Pia Mater 2nd- Arachnoid Layer 3rd- Dura Mater 4th- SkinPia mater is number 7. Gray matter of the cerebral cortex is number 9. White matter of the cerebrum is number 10. Dura mater are number 1 and 2. Subarachnoid space is number 6. Arachnoid mater is number 5. Skull bones is number 8. Arachnoid villi is number 4. Super sagittal sinus is number 3.Cerebrospinal fluid is a transparent, colourless body liquid found in the central nervous system. It is created by specific ependymal cells in the choroid plexuses of the ventricles of the brain, and assimilated in the arachnoid granulations. The cerebrospinal fluid (CSF) from the subarachnoid space is in the end is reabsorbed through out-pocketing into the superior sagittal sinus known as the arachnoid granulations. Arachnoid granulations act as the path for CSF reabsorption into the blood circulation. Location of Cerebrospinal fluid: Cerebrospinal fluid encompasses the brain and the spinal cord. It is contained inside the subarachnoid space and the central channel of the spinal cord. Elevated levels of cerebrospinal fluid (CSF) is found in conditions like meningitis, multiple sclerosis, intracranial hemorrhages etc. Functions of CSF: a) Cushions the brain within the skull and the spine. Acts as the shock absorber of the central nervous system (CNS). It supports the whole CNS. b) Circulates nutrients and chemicals to all the parts of the CNS. c) Help in excretion of waste materials produced in the CNS.
