Document Summary

Ventricles 1 and 2 are the lateral ventricles. In the top diagram: cross section at the top: in the bottom diagram: cross section at the bottom: some parts of the anterior and the posterior. Posterior, anterior and inferior horn of the lateral ventricle. Ventricles are lined with the choroid plexus: producing the fluid that is circulating through the ventricles aka csf: fluid leaves the ventricles and circulates around the brain (like on the outside) Has a flow, and will circulate within the arachnoid space: surrounding the brain (cerebellum included) and the spinal cord: only about 100 to 160 ml of csf within the brain cavity not a lot but important to. Float the brain and act as a cushion: concussion: csf would help cushion the brain a little if stopped abruptly but may not prevent the concussion. Pathway: lateral ventricle interventricular foramen (foramina, a foramen is a hole.
