PAPER 2026 QUESTIONS WITH SOLUTIONS
GRADED A+

●● Neuroglia (glial cells). Answer: Support cells that protect, nourish,
and insulate neurons.


●● Myelin. Answer: Fatty insulating sheath around axons that speeds
nerve conduction.


●● Demyelination. Answer: Loss or destruction of myelin, slowing
nerve impulse transmission.


●● Neurotransmitter. Answer: Chemical messenger that transmits
signals across a synapse.


●● Synapse. Answer: Junction between two neurons where
communication occurs.


●● Blood-brain barrier (BBB). Answer: Selective membrane that
protects the brain from harmful substances.

, ●● Intracranial pressure (ICP). Answer: Pressure within the skull caused
by brain tissue, blood, and cerebrospinal fluid.


●● Increased intracranial pressure. Answer: Elevated pressure within the
skull that can compress brain tissue and reduce blood flow.


●● Cushing's triad. Answer: Late sign of increased ICP: hypertension
(widened pulse pressure), bradycardia, and irregular respirations.


●● Herniation. Answer: Displacement of brain tissue due to severe
pressure.


●● Cerebrovascular accident (CVA). Answer: Sudden impairment of
cerebral circulation.


●● Ischemic stroke. Answer: Stroke caused by blockage of blood flow
to the brain.


●● Thrombotic stroke. Answer: Stroke caused by a clot formed in a
cerebral artery.


●● Embolic stroke. Answer: Stroke caused by a traveling clot that
lodges in the brain.
