  2. Ventricular system - Wikipedia

    en.wikipedia.org/wiki/Ventricular_system

    The four cavities of the human brain are called ventricles. [6] The two largest are the lateral ventricles in the cerebrum, the third ventricle is in the diencephalon of the forebrain between the right and left thalamus, and the fourth ventricle is located at the back of the pons and upper half of the medulla oblongata of the

  3. Fourth ventricle - Wikipedia

    en.wikipedia.org/wiki/Fourth_ventricle

    The fourth ventricle extends from the cerebral aqueduct (aqueduct of Sylvius) to the obex, and is filled with cerebrospinal fluid (CSF). The fourth ventricle has a characteristic diamond shape in cross-sections of the human brain. It is located within the pons or in the upper part of the medulla oblongata. CSF entering the fourth ventricle ...

  4. Third ventricle - Wikipedia

    en.wikipedia.org/wiki/Third_ventricle

    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).

  5. Cerebral aqueduct - Wikipedia

    en.wikipedia.org/wiki/Cerebral_aqueduct

    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.

  6. Choroid plexus - Wikipedia

    en.wikipedia.org/wiki/Choroid_plexus

    In the third ventricle, there is a small amount in the roof that is continuous with that in the body, via the interventricular foramina, the channels that connect the lateral ventricles with the third ventricle. A choroid plexus is in part of the roof of the fourth ventricle.

  7. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The four ventricles, two lateral, a third, and a fourth ventricle, all contain a choroid plexus that produces cerebrospinal fluid. [49] The third ventricle lies in the midline and is connected to the lateral ventricles. [48] A single duct, the cerebral aqueduct between the pons and the cerebellum, connects the third ventricle to the fourth ...

  9. Circumventricular organs - Wikipedia

    en.wikipedia.org/wiki/Circumventricular_organs

    The area postrema is located in the caudal medulla oblongata near the junction of the brainstem and the spinal cord. [16] In humans and in most other mammals that have been studied, it consists of swellings on either wall of the fourth ventricle. [16] [17] In rodents and lagomorphs, however, the area postrema forms a midline structure dorsal to ...
