Ventricles of the brain
Ventricles of the Brain
The Ventricles of the Brain (/vɛnˈtrɪkəlz ɒv ðə breɪn/; from Latin ventriculus, meaning 'little belly') are a group of four interconnected cavities (ventricles) in the brain, where the cerebrospinal fluid (CSF) is produced.
Structure
The ventricular system is composed of 2 lateral ventricles, the third ventricle, and the fourth ventricle. The lateral ventricles are in the cerebral hemispheres. Each lateral ventricle consists of a central body and four horns. The third ventricle is a median (midline) cavity in the brain, bounded by the thalamus and hypothalamus on either side. The fourth ventricle is the most posterior of the ventricular system. It extends from the cerebral aqueduct (aqueduct of Sylvius) to the obex and is filled with CSF.
Function
The ventricles of the brain are a communicating network of cavities filled with CSF, which provides a cushion for the brain, delivers nutrients, and removes waste. The CSF is produced by the choroid plexus, a series of infolded blood vessels that are present within each of the ventricles.
Clinical Significance
Abnormalities or blockages (obstructions) in the ventricles can lead to conditions such as hydrocephalus, where there is an excessive accumulation of CSF. This can cause an increase in intracranial pressure which can lead to brain damage or death if not treated promptly.
