ventrikli

Ventrikli are chambers within the brain that contain cerebrospinal fluid. There are four such chambers in the human brain: two lateral ventricles, a third ventricle, and a fourth ventricle. The lateral ventricles are the largest and are located in the cerebral hemispheres, each communicating with the third ventricle. The third ventricle is a midline structure situated between the two thalami, and it connects to the fourth ventricle. The fourth ventricle lies in the hindbrain, between the pons and cerebellum, and opens to the subarachnoid space, allowing cerebrospinal fluid to circulate throughout the brain and spinal cord.

These ventricles are lined with ependymal cells and are filled with cerebrospinal fluid (CSF), a clear, colorless fluid that plays a crucial role in the central nervous system. CSF provides buoyancy to the brain, protecting it from physical shock. It also helps to remove waste products and toxins from the brain and contributes to maintaining a stable chemical environment for neuronal activity. The production of CSF primarily occurs in specialized structures called the choroid plexuses, which are found within each ventricle. The flow of CSF through the ventricular system is a continuous process, essential for the proper functioning and health of the brain. Disruptions in CSF flow or production can lead to serious neurological conditions, such as hydrocephalus.
