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


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

●● 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
