Arachnoid villi (Protuberances) Liquor outflow into the venous blood
Cerebrum = endbrain - Telencephalon (Cerembrum)
Skull roof - Calvaria
Third ventricle (third ventricle) - Ventriculus tertius
Water ladder - Aqueductus (Aqueduct)
Fourth ventricle (fourth ventricle) - Ventriculus quartus Causes: I - flow obstruction in Area of the aqueduct (The drainage path is blocked due to tumor, abscess, cerebral hemorrhage) II - fluid increase - too much brain water (Liquor) due to cerebral edema (brain swelling) Use external ventricular drainage as a remedy Symptoms: A - nausea, vomiting, Loss of appetite, headache, Fatigue, rigidity with decortication Therapy: B - head must be stored straight C - Medicinal (Diuretics) around the Increase fluid excretion D - puncture of the external CSF spaces (e.g. lumbar puncture) E - External ventricular drainage - Drainage of the brain water
