Lateralventrikel

The lateral ventricles are a pair of C-shaped cavities within the brain, forming part of the ventricular system that contains cerebrospinal fluid (CSF). These ventricles are the largest of the brain's ventricles and are located in the cerebral hemispheres, one in each hemisphere. They are positioned in the frontal, parietal, occipital, and temporal lobes, occupying the central parts of these regions.

Each lateral ventricle consists of a anterior horn (frontal), body, posterior horn (occipital), and inferior horn (temporal). The ventricles are connected to the third ventricle via the interventricular foramen, also known as the Foramen of Monro. The ventricles are lined with ependymal cells and contain a choroid plexus that produces cerebrospinal fluid.

The primary functions of the lateral ventricles include the production and circulation of CSF, which cushions the brain, removes metabolic waste, and maintains intracranial pressure. They also serve as pathways for the flow of CSF throughout the ventricular system and into the subarachnoid space.

Anomalies or conditions involving the lateral ventricles, such as hydrocephalus (excess accumulation of CSF), can lead to increased intracranial pressure and neurological symptoms. Imaging techniques like magnetic resonance imaging (MRI) and computed tomography (CT) are commonly used to evaluate the size and structure of the lateral ventricles for diagnostic purposes.

Understanding the anatomy and function of the lateral ventricles is essential in neurology and neurosurgery, especially in diagnosing and treating various neurological disorders related to CSF dynamics.
