  1. Question 1

    Q1. A 20-year-old patient with a severe head injury is at risk of developing hydrocephalus. Which cerebrospinal fluid (CSF) transport mechanism is most relevant in this scenario?

    • A) Reabsorption at the choroid plexus
    • B) Absorption at the arachnoid villi
    • C) Transport by perivascular drainage
    • D) CSF secretion by the hypothalamus

    Answer: Absorption at the arachnoid villi

    Explanation: Arachnoid villi reabsorb CSF, helping to regulate CSF volume and pressure. USAT, HAT and MDCAT analytical sections repeat this pattern.
