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.
The outer layer of the meninges is called the dura mater or just the dura. The dura is tough and thick and it can restrict the movement of the brain within the skull. This protects the brain from movements that may stretch and break brain blood vessels. The middle layer of the meninges is called the arachnoid.The inner layer, the one closest to the brain, is called the pia mater or just the pia.his protects the brain from movements that may stretch and break brain blood vessels.
