The floor of the central part also has the thalamostriate vein, and the stria terminalis (fibers from the amygdaloid body) and the fornix inferomedially. It is roved by the corpus callosum and floored by the dorsal thalamus and the tail of the caudate nucleus inferolaterally. The central part of the lateral ventricle is located in the region of the parietal lobe. These ventricles have three horns projecting into the lobes for which they are named. There are two C-shaped cavities called the lateral ventricles one in each cerebral hemisphere. This article will look at the structure of this system and how it helps the brain.īody of lateral ventricle, Corpus ventriculi lateralis Right & left lateral aperture (Luschka): fourth ventricle -> subarachnoid space Median aperture (Magendie): fourth ventricle -> subarachnoid space Interventricular foramina (Monro): lateral ventricles -> third ventricleĬerebral aqueduct (Sylvius): third ventricle -> fourth ventricle Suprasellar (chiasmatic), interpeduncular, prepontine, cistern of the corpus callosum Roof - superior and inferior medullary vela of the cerebellum Supraoptic recess (superior to the optic chiasma), infundibular recess (superior to the pituitary infundibulum), suprapineal recess (superior to the pineal gland), pineal recess (protrudes into the pineal infundibulum) Key facts Lateral ventriclesīody, anterior (frontal) horn, posterior (occipital) horn, inferior (temporal) horn, There are four such hollow spaces in the brain that house cerebrospinal fluid (CSF): two lateral ventricles, a third ventricle and a fourth ventricle.
The fluid (cerebrospinal fluid) is produced in the ventricular system of the brain. This space is therefore occupied by a clear fluid that suspends the brain within the cranial vault. However, even with all those layers, there is still space surrounding the brain that makes it vulnerable to injury. To add even more protection, the brain is wrapped in three meningeal layers – dura mater, arachnoid mater and pia mater. The human brain is so vital and delicate that it is fully encased in a bony vault in order to protect it from damage.
