which statement is true regarding cerebrospinal fluid?
if csf is not properly resorbed, the result would be hydrocephalus.
there is about a liter of csf within the brain and spinal cord.
csf is made during fetal development and does not change through the lifetime of the person.
csf moves back into the blood supply by the process of osmosis.
csf is identical in composition to blood plasma.

Explanation:

• Hydrocephalus occurs when cerebrospinal fluid (CSF) is not properly resorbed. The normal volume of CSF in the brain and spinal cord is about 150 - 160 ml, not a liter. CSF is continuously produced and modified throughout life. CSF moves back into the blood supply mainly via arachnoid villi (not just osmosis). CSF has a different composition from blood plasma (e.g., lower protein content).

Answer:

If CSF is not properly resorbed, the result would be hydrocephalus.
