Hydrocephalus mechanism
Web14 apr. 2024 · The optic nerve develops as an outgrowth of the diencephalon. Therefore, like the rest of the central nervous system (CNS), it is protected by derivatives of the brain meninges and washed by cerebrospinal fluid in the subarachnoid space. This arrangement differs from other cranial nerves. Web4 jun. 2024 · Hydrocephalus can be defined broadly as a disturbance of cerebrospinal fluid (CSF) formation, flow, or absorption, leading to an increase in volume occupied by this fluid in the central nervous...
