Question

Quizplus · Accepted Answer

Cerebrospinal fluid circulates within the subarachnoid space, which is located between the arachnoid mater and pia mater of the meninges, and also within the central canal of the spinal cord. CSF is formed within the ventricles of the brain by the choroid plexus and is not formed from the blood within the dural sinuses. CSF primarily contains water, electrolytes, and small amounts of other substances, such as glucose and proteins. There is no blood in CSF under normal circumstances.
