The ventricles are filled with cerebrospinal fluid (CSF) which bathes and cushions the brain and spinal cord within their bony confines. CSF is produced by modified ependymal cells of the choroid plexus found in all components of the ventricular system except for the cerebral aqueduct and the posterior and anterior horns of the lateral ventricles.
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 ridge was originally described by anatomists as the calcar avis, while the ridge running along the floor of the temporal horn of the lateral ventricle was described by various names, in particular as the hippocampus.
Its role as a neuroendocrine structure associated with the ventricular system qualifies it for classification as a CVO. [1] Related to its secretory function, the SCO is partially composed of ependymal cells. [1] [30] These ependymocytes are characterized by elongated cell bodies that contain secretory materials and are covered in cilia.
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). [1]
Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.
The suprapineal recess is an anatomical structure in the ventricular system of the brain. It is located in the posterior part of the third ventricle , overlying the cerebral aqueduct . [ 1 ]
