The ventricular system is made up of four ventricles connected by narrow passages. Normally, CSF flows through the ventricles, exits into cisterns (closed spaces that serve as reservoirs) at the base of the brain, bathes the surfaces of the brain and spinal cord, and then reabsorbs into the bloodstream.

Brain ventricle: One of the communicating cavities within the brain. There are four ventricles: two lateral ventricles, the third ventricle, and the fourth ventricle. The lateral ventricles are in the cerebral hemispheres. Each lateral ventricle consists of a triangular central body and four horns.

1- Supports and cushions the brain and spinal cord. 2- Removes metabolic waste products through absorption; the site of the greatest absorption are the arachnoid villi. 3- Controls brain excitability by regulating the ionic composition. 4- Serve as a pathway for pineal secretion.

In these cases, brain tissue may actually shrink. NPH is an abnormal increase of cerebrospinal fluid in the brain's ventricles that may result from a subarachnoid hemorrhage, head trauma, infection, tumor, or complications of surgery. However, many people develop NPH when none of these factors are present. An estimated 375,000 older Americans have NPH.

The term hydrocephalus comes from the Greek words “hydro,” which means water, and “cephalus,” meaning head. Simply put, hydrocephalus is excessive accumulation of fluid in the brain. While once known as “water on the brain,” the “water” is actually cerebrospinal fluid (CFS). The excessive accumulation of cerebrospinal fluid (CSF) results in an abnormal widening of spaces in the brain called ventricles.

The standard treatment, a shunt, was developed in 1956 and has a 50% failure rate after just two years which is the reason so many have to have multiple brain surgeries just to stay alive. 60% of children with hydrocephalus are not independent as adults and require assistance.

The Ventricular System. Within the brain there are four ventricles: two lateral (meaning away from the midline of the body), a third ventricle near the center of the brain and the fourth ventricle under the cerebellum. They are all connected by smaller passageways that allow the CSF to circulate slowly among them.

Brain ventricles. Your brain floats in a bath of cerebrospinal fluid. This fluid also fills large open structures, called ventricles, which lie deep inside your brain. The fluid-filled ventricles help keep the brain buoyant and cushioned.

The brain controls our thoughts, memory and. speech, movement of the arms and legs, and the. function of many organs within our body. It also. determines how we respond to stressful situations. (such as taking a test, losing a job, or suffering an. illness) by regulating our heart and breathing rate. Nervous system.
