Cerebrospinal Fluid Quiz

What is the primary role of the central canal of the spinal cord?

• To store cerebrospinal fluid (CSF)

• To provide a pathway for CSF circulation

• To produce white blood cells

• To transmit nerve signals

What are the main components of cerebrospinal fluid (CSF)?

• Water, glucose, and red blood cells

• Water, electrolytes, glucose, proteins, and white blood cells

• Water, sodium, and lipids

• Water, potassium, and fats

Through which structure does CSF flow from the lateral ventricles to the third ventricle?

• Cerebral aqueduct

• Interventricular foramen

• Arachnoid villi

• Dural sinuses

What is the function of arachnoid villi?

• To produce CSF

• To absorb CSF into the bloodstream

• To cushion the brain

• To transport nutrients

Where are dural sinuses located?

• Within the brain tissue

• Between the layers of the dura mater

• Inside the spinal cord

• In the subarachnoid space

Which of the following is a function of CSF?

• Producing red blood cells

• Cushioning the brain and spinal cord

• Transmitting nerve impulses

• Storing nutrients

How does CSF provide buoyancy to the brain?

• By increasing the brain's weight

• By reducing the effective weight of the brain

• By absorbing nutrients

• By maintaining homeostasis

What role do dural sinuses play in the circulation of CSF?

• They produce CSF

• They collect venous blood and CSF from the brain

• They transport CSF to the spinal cord

• They store CSF

Which of the following is NOT a function of CSF?

• Transporting nutrients

• Maintaining homeostasis

• Producing hormones

• Providing buoyancy

What is the role of the subarachnoid space in CSF circulation?

• It stores CSF

• It surrounds the brain and spinal cord with CSF

• It produces CSF

• It absorbs CSF into the bloodstream
