We need to be knowledgeable about the anatomy of the brain and its coverings to comprehend two consequences of brain injuries, hematomas. Imagine a magician on drilling into an individual’s brain with an electrical drill intention. What layers will the drill experience the mind to its destination? The drill will pass across the skin and then before entering a series of 3, the skull membranes containing the meninges. In sequence, the 3 membranes are the dura mater, the arachnoid mater and the pia mater and after that finally the brain itself. Subdural and epidural hematomas are alike because they’re masses of blood deposited outside the mind and caused by head injury but inside the skull.
They differ from their places. An epidural hematoma lies outside the dura mater, while a hematoma lies within the dura mater and outside the mater. Hence, the two types of hematoma’s places are encoded in their names, epi is Greek for sub and upon is Latin for below. There is of hematoma A sort intracerebral hemorrhage. These are no less severe than people outside the mind and happen within the brain tissue, but are not the topic of the essay. Ruptures of blood vessels produce hematomas. Epidural hematomas are often caused by bleeding from an artery which nourishes the meninges known as the central meningeal artery, even though subdural hematomas, therefore, are usually due to bleeding from veins that drain blood away from the surface of the mind.
However, another difference between epidural and subdural hematomas is exactly what they look like on computed tomographic scans. When the bleeding was latest, both show up as intensely luminous objects on the scan, but the forms of the blood clots are very different. In epidural hematomas, whose blood is more limited from its spread because it’s to push harder to move outwards in the tight space between the interior surface of those skulls and those outer surface of that dura mater.
In contrast, the bleeding which generates subdural hematomas is more free to spread from the freer space beneath the dura mater and usually runs from the front of the brain to the rear. One problem that applies to both types of hematomas is they occupy space, sometimes a lot of it, inside the cranium where there isn’t a lot of additional space to go around. As they expand they compress the mind tissue next to them and further increase the pressure inside the skull which can harm the rest of the brain.
