In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [1] [2] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle ...
Classified as a sensory circumventricular organ (along with the SFO and AP), [13] the vascular organ of lamina terminalis (VOLT) is situated in the anterior wall of the third ventricle. [22] Characteristically of the CVOs, it lacks the tight endothelial blood brain barrier.
For a number of substances, the BCSFB is the primary site of entry into brain tissue. [14] The blood–cerebrospinal fluid barrier has also been shown to modulate the entry of leukocytes from the blood to the central nervous system. The choroid plexus cells secrete cytokines that recruit monocyte-derived macrophages, among other cells, to the ...
Within the ventricles of the brain, a population of modified ependymal cells and capillaries together known as the tela choroidea form a structure called the choroid plexus, which produces the CSF. [5] Modified tight junctions between epithelial cells control fluid release. This release allows free exchange between CSF and nervous tissue of ...
In the brain, the interventricular foramina (foramina of Monro) are channels that connect the paired lateral ventricles with the third ventricle at the midline of the brain. As channels, they allow cerebrospinal fluid (CSF) produced in the lateral ventricles to reach the third ventricle and then the rest of the brain's ventricular system.
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]
Fourth ventricle location shown in red (E), pons (B); the floor of the ventricle is to the right, the roof to the left. The fourth ventricle has a roof at its upper (posterior) surface and a floor at its lower (anterior) surface, and side walls formed by the cerebellar peduncles (nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side).
The third ventricle is one of the four connected cerebral ventricles of the ventricular system within the mammalian brain. It is a slit-like cavity formed in the diencephalon between the two thalami , in the midline between the right and left lateral ventricles , and is filled with cerebrospinal fluid (CSF).
