12 Questions
What is the main mechanism of absorption of cerebrospinal fluid (CSF) in the body?
Filtration due to pressure gradient between hydrostatic pressure in the subarachnoid space fluid and the pressure in the dural sinus blood
How much CSF is typically formed and absorbed by the body daily?
500ml
What effect does coughing have on cerebrospinal fluid (CSF) pressure?
Increases pressure by decreasing absorption
Which event can increase cerebrospinal fluid (CSF) pressure by compressing the Internal Jugular Vein?
Compression of Internal Jugular Vein
What is the protective function of cerebrospinal fluid (CSF) related to brain injuries?
Acts as a cushion preventing brain damage from shock
In the case of a severe blow to the head, what injury pattern may occur due to the movement of the brain against the skull bone?
Counter coup injury
What is the primary function of the medium of exchange between blood and brain tissues?
Regulation of cranial content volume
Which procedure involves passing a needle between the occipital bone and atlas to collect cerebrospinal fluid?

In lumbar puncture, why is the lumbar region preferred for introducing the needle into the subarachnoid space?
To widen the subarachnoid space
What constitutes an essential purpose of collecting cerebrospinal fluid through cisternal or lumbar puncture?
