explain which space each of the following hematomas would be located within and briefly describe the key symptoms associated with each a. epidural hematoma b. subdural hematoma c. subarachnoid hematoma

epidural hematoma- - the skull is damaged at pterion and the sharp edges of the bone damage the middle meningeal artery, which normally supplies the dura mater with blood. - When this artery is cut, it releases blood that begins pushing the dura mater away from the skull, pooling into a mass of blood that can compress the brain. - as blood begins to pool between the dura mater and the skull, they will begin to complain of dizziness, headache, nausea, possibly blurred vision, - if not treated, they will lose consciousness and could die. - pooled blood must be removed in order to free the brain from compression. subdural hematoma- - Bridging veins carry blood away from the brain and into the dural venous sinuses. - falling down or experiencing rapid movement can cause these veins to shear, resulting in their leaking venous blood. - most common site of this shearing is below the dura mater and above the arachnoid mater, causing blood to pool there in what is known as a subdural hematoma. - Because venous blood travels under less pressure than arterial blood, the onset of symptoms can take days to be noticed. Most people just experience a dull headache that won't go away. subarachnoid hematoma- -occurs when the arteries supplying blood to the brain burst or are otherwise damaged. - These arteries are found in the subarachnoid space, and one of the most common causes of arterial rupture in the brain is hypertension. When an artery in the subarachnoid space bursts, there is a huge spike in intracranial pressure,The most common site of this shearing is below the dura mater and above the arachnoid mater, causing blood to pool there in what is known as a subdural hematoma. Because venous blood travels under less pressure than arterial blood, the onset of symptoms can take days to be noticed. Most people just experience a dull headache that won't go away.
