Question

question 1 (mandatory) (10 points) the mechanism of hydrocephalus caused by arnold - chiari malformation is: deficient absorption of csf obstruction due to tonsillar herniation inflammation overproduction of csf

Explanation:

Arnold - Chiari malformation involves the downward herniation of the cerebellar tonsils through the foramen magnum. This tonsillar herniation obstructs the normal flow of cerebro - spinal fluid (CSF), leading to hydrocephalus. Deficient absorption, inflammation, and overproduction of CSF are not the main mechanisms in this case.

Answer:

B. Obstruction due to tonsillar herniation
