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.
1 The dura mater is the âtoughestâ layer, and the pia mater is the âsoftestâ layer. 2  The arachnoid layer is filled with a web of collagen. 3  All together these three layers are called the meninges. 4  The arachnoid layer + pia mater layer is called the leptomeninges.his layer of protective tissues is collectively named the â meninges â but is actually composed of 3 main layers: The Dura mater, the Arachnoid layer, and the Pia mater. Meninges.
