A. Vermis
B. Cortex
C. subcortical white matter
D. 4 pairs embedded nuclei
E. 3 cerebellar peduncles: myelinated fibers transmit signals in/out cerebellum

17
Q

Brainstem

A
  1. Midbrain
    A. Superior and inferior colliculi
    B. Cerebral aqueduct (of Sylvius)
    C. Crus cerebri (cerebral peduncle)
18
Q

Ventricular system in the brain

A
  1. Lateral ventricle (paired) -> interventricular foramen (foramen of Munro)
  2. Third ventricle (single): choroid plexus = roof -> cerebral aqueduct (of Sylvius)
  3. Fourth ventricle: choroid plexus = roof
  4. Central canal of spinal cord cont w/ ventricular system
  5. Forth ventricle -> subarachnoid space via
    A. Median aperture (foramen of Magendie)
    B. Paired lateral aperture (foramina of Luschka)
  6. CSF thru subarachnoid space to bathe brain/spinal cord -> arachnoid granulations -> dural venous sinuses
