(206) Waste pipe and special waste means any pipe which receives the discharge of any fixture (except water closets or similar fixtures) and discharges to the house drain, soil or waste stacks. When such pipe does not connect directly with a house drain, waste or soil stack, it is termed a special waste.
As with the other ventricles of the brain, it is filled with cerebrospinal fluid, which helps to protect the brain from injury and transport nutrients and waste. The third ventricle is a narrow cavity that is located between the two halves of the brain. The third ventricle sends messages to and receives messages from the lateral ventricles, which are located in front of the third ventricle, and the aqueduct of the midbrain, which is located directly behind the third ventricle. The hypothalamus and thalamus are located on the sides of the third ventricle. Abnormalities of the third ventricle are associated with various conditions including hydrocephalus, meningitis, and ventriculitis. Hydrocephalus is an excessive buildup of fluid on the brain.
Here we will discuss the parts of the brain with reference to the cerebrum, the diencephalon, the cerebellum, and the brain stem. The brainâs four ventricles are called, in turn, the two lateral ventricles, the third ventricle, and the fourth ventricle.
