A void contract can be one in which any of the prerequisites of a valid contract is/are absent for example if there is no contractual capacity, the contract can be deemed as void. In fact, void means that a contract does not exist at all.
The ventricular system is a set of four interconnected cavities (ventricles) in the brain and the location of CSF production. This system is continuous with the central canal of the spinal cord. The system comprises four ventricles: right and left lateral ventricles (the first and second ventricles) third ventricle.
The ventricles are a series of cavities filled with CSF. The majority of CSF is produced from within the two lateral ventricles. From here, the CSF passes through the interventricular foramina to the third ventricle, then the cerebral aqueduct to the fourth ventricle.
