this's we do with government engineers of the brain and spine before that's within by are in treating ourselves with the smarter. So if somewhere someone going to make incisions in the shape of a requirement of the double fist and then individually dissected all it delivers, this is what we get. No, the front of the specimen that I'm dealing with you would be this, and this would be today on this would be the left. The specimen is also a weight like this screen completed. That means it's a very good for revising the scab there's of the steps and do it. Then you went back to the meninges. So the meninges are these membranous layers that covered the brain and spinal cord. There's three different layers. The door, a martyr, the record water on the pier. Beginning with the dura mater. It has studios very austere course of position on the men into a little steep. Uh, the Dulera is south for most memory, and it's quite tough in characteristic, so it's sort of yeah, uh, these two layers off the directions separate form spaces, which are called Sinuses, and they're filled with this plan. So when you're showing here is the superior sided Sinus, which is the biggest one. But there's others you can see in this image over here, so but on liver, the one over here is this one. Superior. It's a little Sinus. The dura also forms falls in the brain so you can see that and in Julia's, are sort of combining to fall. It's full of urine, just called the fire. Celebrate it separates the right and left atmospheres. That's important made structures, stability. There's another one retreat can see in this image. Aureus for the tentorium cerebella On this separate, it stops pretty loves and terrible, um, on brain stem moving on the court. The arachnoid members, which is showing you it, has fired the leg projections with surgeries, and it's named it at night, and you can see them over here on the space. The suburbs in space would typically be filled with CSF cerebrospinal fluid, which is important for both protection as well. This nutrition, often in Academy American minutes, they're associates. There's no CSF, so there are no remember. It sort of collapses onto the surface of the brain. So if you were look at the specimen you will be seeing their backside and then you. The arachnoid also forms the's projections. Rich are important to miss rejection, called an accurate foundations or something scored attack mode with that on their important so that the cerebrospinal fluid country training So the venous blood the next year is the be a lot of it is on the two cent data, and it's quite delicate. Stack. You did it through this office of the brain Close arrangement off these off. The meningitis were less consistent in the spinal cord as well. But there is one significantly and that's the president's off epidural space. This you can see that if this is the door and there is no space between the spells on delivered at the spine before you have the spacer on this systemically significant because epidural anesthetics can be administered in to this area in the fall on. If you are interested more and how this happens, you can such Epiduo that uncompleted Afghan scroll down on What's this particular we do? That's it. Thank you
