Lenz's Law. Lenz's Law - seeing that the magnetic field induced by a current induced by a change in magnetic flux (Faraday's Law) counteracts the change in flux.
The brain is protected from injury by the skull, meninges, cerebrospinal fluid and the blood-brain barrier. In this post we will explore them all in detail, well, except for the skull since that was already discussed in other posts about the bones. The function of the meninges is to cover and protect the brain itself. It encloses and protects the vessels that supply the brain and contains CSF between the pia mater and arachnoid maters. Immediately deep to the periosteum is the periosteal and meningeal which create the dura mater. The dura mater is found all around the brain and its 2 layers separate and create spaces called dural sinuses.
CSF also acts as a transport system that delivers nutrients to different parts of the central nervous system, and also removes waste products. There are three layers to the meninges: Dura mater: The outermost membrane, this is the thickest of the three layers and has both an outer and inner layer. It is one of the few structures of the skull capable of feeling pain. The brain itself cannot.
