The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, [3] allowing for the flow of CSF to circulate. [3] [4] All of the ventricular system and the central canal of the spinal cord are lined with ependyma, a specialised form of epithelium connected by tight junctions that make up the blood ...
This allows cerebrospinal fluid produced in the lateral ventricles to reach the third ventricle and then the rest of the brain's ventricular system. [1] The walls of the interventricular foramina contain choroid plexus, a specialized structure that produces cerebrospinal fluid. The choroid plexus of the third ventricles continues through the ...
Within each developing radial unit, the process of neurogenesis gives rise to post-mitotic (non-dividing) cortical neurons, which begin the process of radial neuronal migration from the ventricular zone and adjacent subventricular zone to form the cortical plate in the classic 'inside-out' manner beginning with the deep cortical layers.
Protruding into the third ventricle of the brain, the highly vascularized SFO can be divided into 3–4 anatomical zones, especially by its capillary density and structure. [ 25 ] [ 26 ] The central zone is composed exclusively of the glial cells and neuronal cell bodies.
The cerebral aqueduct (aqueduct of the midbrain, aqueduct of Sylvius, Sylvian aqueduct, mesencephalic duct) is a small, narrow tube connecting the third and fourth ventricles of the brain. [ 1 ] [ 2 ] The cerebral aqueduct is a midline structure that passes through the midbrain .

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).
The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain. It runs as a sheet from the corpus callosum down to the fornix. The septum is not present in the syndrome septo-optic dysplasia.
