Guten Tag everyone! Hope you are doing fine cause I am not. It’s just the sulci of my life (downs!) and hope to encounter my gyri (ups) soon. Nevertheless, we are going to talk about the things that matter. The “maters” of the brain and spinal cord. The word mater means ‘mother’, it signifies support and protection. I have mentioned ‘meninges’ several times, hence we know that meninges are the tissue layers surrounding B and SC. Sure, you can call them bodyguards of our President and Prime minister, but their role is not only limited to protection. They are much more than that. Let’s dive in to learn more about meninges.
There are 3 types of meninges or membranous envelopes…Dura Mater, Arachnoid Mater and Pia Mater. Chronology samajhiye…. Outermost is the dura mater, as the name suggests it is a strong, durable, thick and dense membrane…followed by dura is arachnoid, mesh-like and then comes pia, tightly adhering to the brain and spinal cord tissue. These membranes help our gooey mass of brain to have structure….dura separates the two hemispheres, arachnoid provides nourishment and pia checks the permeability of a substance entering. It is a pretty neat system. These maters run across the nervous system until, filum terminale…which literally means, endpoint.
Let’s see the fun facts about these motherly membranes. A fish is having only one meninx (singular for meninges), frog-snakes have 2 and birds and mammals have 3! God Bless us! Do you know there are specialized meningeal arteries and veins for these meningeal layers? Between arachnoid and pia mater…known as “Subarachnoid space” the magic potion is being formed and circulated? That’s right…CSF has a passage through these layers….just like the Nagini from Chamber of Secrets (shout out to Harry Potter fans!)….I am telling you folks everything has a reason and purpose. Especially in your body, nothing is unnecessary or extra. If you think body and spirituality are two polar opposite things, see for yourself, your body is an example of many spiritual laws itself! It fascinates me when people embark on a spiritual journey without actually knowing their bodies. Start with the outside and you will understand your inner being in a better way. You will understand, numerous cells and physiological reactions are happening, tons of energy is created, utilized and transformed….you will appreciate this energy flow. For cells, it doesn't matter if you’re having a bad day or a good day…all they know is orders and execution. You should try it sometimes…experiencing this flow…no seriously! You can do it just by closing your eyes and shutting other senses temporarily….give it a try…nothing bad is going to happen when you have got bodyguards in place.
well brain stuff is not easy. but I still tried to understand this.✌️😅
