Meninges of Brain | Dura mater, Arachnoid mater, Pia mater| spaces between meninges

Explore the detailed anatomy of the meninges, the protective coverings of the brain and spinal cord. In this comprehensive video, we explain the three layers of meninges—dura mater, arachnoid mater, and pia mater—and the spaces between them (epidural, subdural, and subarachnoid spaces). Learn their structural significance, clinical importance, and their roles in the central nervous system. A must-watch for medical students and healthcare professionals!

The dura provides the brain and spinal cord with an extra protective layer, attaches the brain to the skull and the spinal cord to the vertebral column to keep them from being jostled around, and provides a system of veinous drainage through which blood can leave the brain. The arachnoid mater gets its name because it has the consistency and appearance of a cobweb. It is much less substantial than the dura. Strands of connective tissue called arachnoid trabeculae stretch between the arachnoid and pia mater. These help to suspend the brain in place. Between the arachnoid and pia mater there is also an area known as the subarachnoid space, which is filled with cerebrospinal fluid. The pia mater is a thin layer that closely follows the contours of the brain. It forms a tight membrane around the brain and spinal cord, acting as an an additional barrier and aiding in the secretion and containment of cerebrospinal fluid. Blood vessels are held against the pia mater by connective tissue before they penetrate the brain. There is a space between the dura of the spinal cord and the bone of the vertebral column known as the epidural space; analgesics and anesthesia are sometimes administered here. Also, the dura and arachnoid mater extend several vertebrae below the end of the spinal cord, creating a cerebrospinal fluid-filled area called the lumbar cistern where there is no spinal cord present. Cerebrospinal fluid can be withdrawn from here because a needle can be inserted with little risk of damaging the spinal cord. Thus, the lumbar cistern is the site where cerebrospinal fluid is aspirated in a lumbar puncture, also known as a spinal tap. This is done, for example, to diagnose meningitis, a potentially life-threatening inflammation of the meninges. #ninjanerd #BrainAnatomy #neurodiversity #HumanBrainAnimation #IkenEdu #AnatomyOfTheHumanBrain #bellspalsy #cranialnerveexam #humananatomy #learning #humananatomy #headandneckanatomy #study #learnanatomy #facial #bellspalsy #trigeminal #cranialnerves #cranialnerveexam #bdchaurasia #skull #bones #carotid #medicalmnemonic #medicalmnemonics #rhesusmedicine #studymedicine #studygram #medstudent #medicalschool In this video tutorial we will learn about the dura mater. The dura mater (lat. 'hard mother') is a thick and fibrous membrane, forming the outermost layer of the meninges, the other layers being the arachnoid and pia mater. The two layers of the dura mater separate from each other in some places forming dural infoldings: Falx cerebri Tentorium cerebelli Falx cerebelli Diaphragma sellae Medical students flip cadaver in dissection hall #viral #lifelessons #movieclips #shorts #viralshorts #viralvideo #baby #babygirl #viral #pregnany #video #doctor #medical #vlog #facts #emargency
