What is sub brachia hemorrhage?
I think you are referring to "sub-arachnoid hemorrhage". This is a type of brain hemorrhage occurring underneath the arachnoid membrane which envelopes the brain and can be caused by bleedding from an aneurysm
What is ventral sub arachnoid space?
arachnoid space
What function reabsorbs cerebral spinal fluid back into the blood?
arachnoid granulations Normally the pressure of the CSF is higher than that of the venous system, so CSF flows through the arachnoid villi and granulations into the blood
What is the intermediate layer of the meninges?
middle layer of meninges is called arachnoid
What is a sub arachnoid hemorrhage?
A subarachnoid hemorrhage is an intracranial hemorrhage into the cerebrospinal fluid-filled space between the arachnoid and pial membranes on the surface of the brain. The cause may be trauma, rupture of an aneurysm, or an arteriovenous anomaly. The hemorrhage may extend into the brain if the force of the bleeding from the broken vessel is severe or sudden. Localized pain usually results from vascular injury and/or distortion.
What MRI misses that CT scan shows?
The classic answer is acute sub-arachnoid hemorrhage.
What is the space between the pia mater and the arachnoid membrane called?
That space is called as sub arachnoid space. It is filled with cerebrospinal fluid.
What contains a delicate network of collagen and elastin fibers through which cerebrospinal fluid circulates?
The arachnoid and sub-arachnoid spaces.
Which body cavity the needle to be inserted in spinal tap?
The sub-arachnoid space (within the inner layer of the dura).
What will be the result if the fourth ventricle is blocked?
if the fourth ventricle is blocked it will result in accumulation of CSF and there is no drainage of CSF into the sub -arachnoid space.
What drains cerebrospinal fluid in to venous blood in the dural sinus?
The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.
Which layer of the meninges resembles a spider web?
The middle element of the meninges is the arachnoid membrane
