The third ventricle is a narrow, slit-like ventricle located between the two lateral ventricles and connects them to the fourth ventricle.

The fourth ventricle is a diamond-shaped ventricle located at the base of the brain and connects to the central canal of the spinal cord.

The lateral ventricles, located within the cerebral hemispheres, are the primary sites of cerebrospinal fluid production.

The choroid plexus is responsible for producing and secreting cerebrospinal fluid into the ventricles.

The aqueduct of Sylvius, also known as the cerebral aqueduct, connects the third and fourth ventricles.

Ependymal cells lining the ventricles facilitate the transport of nutrients and waste products between the cerebrospinal fluid and the brain tissue.

The foramen of Magendie is one of the three foramina that connect the fourth ventricle to the subarachnoid space.

Hydrocephalus is a condition characterized by an excessive accumulation of cerebrospinal fluid in the ventricles, leading to increased pressure within the brain.

The lateral ventricles are located within the cerebral hemispheres and are the largest of the ventricles.

The foramina of Luschka are two small openings that connect the fourth ventricle to the subarachnoid space.

The fourth ventricle is responsible for draining cerebrospinal fluid into the subarachnoid space through the foramina of Luschka and Magendie.

The septum pellucidum is a thin membrane that separates the lateral ventricles.

The lateral ventricles are located beneath the corpus callosum, which is a thick band of nerve fibers connecting the two cerebral hemispheres.

Hydrocephalus is a condition characterized by an excessive accumulation of cerebrospinal fluid in the ventricles, leading to increased pressure within the brain.

The third ventricle is located at the junction of the diencephalon and mesencephalon, and it connects the lateral ventricles to the fourth ventricle.
